The subject of the invention is a storable l-komponentige mass on the basis of monomerer, oligomerer and/or polymere connections and or several the hardening a serving component (n), whereby at least the monomers, activatable by mechanical and/or physical forces, oligomere and/or polymere and/or the hardening serving component (n) is contained in an s a reaction-preventing sleeve (is). The masses can if necessary exhibit a content of further components. The subject of the invention is also a procedure for the production, activation and application of such more activatable l-komponentigen masses. Reactive Zweiund multi-component masses is in practice sufficiently well-known. Among them one understands generally systems, with which with one another reacting the connections geI0 separates packaged are stored and shortly before application, e.g. by merging these components, to the reaction are only brought. It is further well-known that such reactive Zweiund can harden and/or polymerize multi-component masses to high-quality materials, bonding agents, and such, which are generally estimated. However this Zweiund of multi component systems possesses still another number of salient disadvantages, which are extraordinarily hinderlich an intensified employment in many ranges of the technology and the handicraft. These disadvantages are the among other things following: - critical mixing proportion, - mistakes in mixing, - short or to long Topfund working times, - larger mixture beginnings supply strong exotherms reactions, - to long hardening times, - complex and/or expensive Zweiund MehrkomponentenDosierund Mischeinrichtungen, - physiological precariousnesses with many reactive lugs. It was not missing in the last years at efforts, around these disadvantages by the development of Eintopfbzw. To replace Einkomponentensystemen with similar characteristics. In individual areas these efforts led to a partial success, which applies in particular to the Einkomponentensysteme re-activatable by air humidity on the basis of silicone rubber, PU and polysulfide. However many Zweiund of multi component systems cannot be reformulated into humidity-hardening systems for different reasons. Independently of it humidity-hardening systems have among other things the disadvantages that Vulkanisationsund hardening speeds is very slowly (several days) and these again on the 5chichtstärke and/or on the relative air humidity of the environment dependent. In recent time to the intensified extent it was therefore tried to solve these and other disadvantages in the way that at least one of the reactants and/or reaction initiators in reaction-preventing sleeves is present. The casing with chemically inert wall materials takes place either in a liquid or firm phase, whereby one avails oneself however today of preferably well-known encapsulation technologies, in particular the micro packaging technologies, in order to come to rieselfähigen products from small grain size to. Therefore below for the sake of simplicity preferably spoken of micro caps and microencapsulated lugs, although thereby completely generally sleeves are to be understood. For the achievement of a temporarly effective reaction preventing the sleeves must fulfill a multiplicity of demands, whereby for the employment of lugs microencapsulated new parameters are created. This result to new ready one from because the sleeves and/or. Wall materials depending upon targeted application among other things - chemically inertly in relation to the inside and the outside phase, - diffusion, - break-proof, flexibly and/or flexibly and/or temperature stable to be must. So that the sleeves and/or wall materials of the micro caps can fulfill the above and other demands, they are subjected different subsequent treatments. These subsequent treatments of the micro cap walls can insist among other things of specific Schrumpfungsund hardening methods, in addition, in drawing up secondary walls on the sleeves or other manipulations. In this way leave itself break-proof, diffusion-close and storable sleeves to create, which however among other things disadvantage possess that they are with difficulty aufbrechund destroyable with the application of masses, in which they are contained. This is valid in besenderem measure for cap spectra < 600 m, preferably < 300 M. straight lines with small micro cap sizes are sufficient pressures and/or shearing stresses often even strongly not superelevated, in order to destroy it. Furthermore no simple aids and performing are to practice at the disposal, which are able, to produce so high pressures in order to break the sleeves. Completely apart from the fact that thereby the tools, materials and such can be strongly deformation and damaged. A further disadvantage is given with manufacturing and camps of such masses, which contain mfkroverkapselte materials. 'This is valid in particular for masses, which are based on systems of high viscosity, thixotropy and/or high filling degree, in particular with granular and/or spitzigen waddings. Because the shearing stresses often arising with the Misehvorgang necessary and are so large that they can blow up at least partially sleeves and initiate the reactive materials unwanted premature reactions flowing out then. When storing in particular masses geflJllten with specifically heavy fillers similar partial cap destruction is to I0 observes, because the high dead weight of the mass presses permanently on the sleeve walls and exceeds its pressure strength value. Those managing described and other further disadvantages admits nascent Einkomponentensysteme, in those mikroverkapse! Te reactive materials are contained, can in the following salient, negative characteristics be essentially summarized: I. Due to high frictions, temperatures and/or such at least partial micro cap break develops when training micro caps into a mixture. 2. When storing masses, which are filled with specifically heavy fillers, cap break arises due to the high dead weight. 3. Zeitund the temperature-dependent mechanical and/or physical forces in the application place are not often enough to come out over to a still justifiable micro cap breakup ratio. In the DE-OS 2526603 polysulfide masses are descriptive, microencapsulated Vernetzungsbzw. Vulcanizing agents contain. With these vulcanizing agents it concerns well-known materials, like lead dioxide, manganese dioxide, zinc peroxide, Cumolhydroperoxyd and such such microencapsulated itself vulcanizing agent containing polysulfide masses is single-component and is the application in the processing place to facilitate. By the homogeneous distribution of the Vulkanisatlonsmittels in a reaction-preventing sleeve it should be guaranteed that the activated masses supply to building stretch joints Vulkanisate, which are early stressable compared with that today well-known 2-components systems. Out of the writing it goes further hevor that the micro cap size does not < 400 over, preferably does not < 600 over, to be may do, since to small M are with difficulty destroyable krokapseln. Furthermore these sealants with one are for instance IO to 20 igen surplus of Vernetzungsbzw. To provide vulcanizing agents, so that all SH-groups the polysulfide polymers are oxidized. To large micro caps against it knew an unfavorable distribution degree of the hardener and/or vulcanizing agent in the mass and with interfering into the mass to be already partially destroyed. Since the destroying us ratio is not calculable with the mixture process, the quality of such masses is left to the coincidence in this procedure. The activation takes place in an activation device. This Aktivierungsund destruction device consists of a chopper and a screw conveyor, which are arranged behind the squirting out nozzle of a spray gun. Practice showed however now that such a mechanical device is not sufficient, in order to obtain a high cap destruction ratio. It lies on the average < 60%. In order to receive reproducible Vulkanisate with continuous characteristic values, however a cap destruction ratio is > 80%, in particular > 90%, necessarily. A further economic disadvantage is &lt by the preferential use of microspheres; 400 over given. Since however with that today well-known micro packaging technologies with the microencapsulation of such vulcanizing agents to a large extent also micro caps with a grain size < 400 over does not result those to be used can, additionally the economic result is affected negatively. Described in the DE-OS 2536319 for the first time new ways could be used, like such materials containing l-Komponentenmassen which were valid manufactured, activated and. The theory of this invention is based on the realization that into these masses inorganic and/or organic micro hollow bodies are trained, which take over thereby following functions and/or tasks: I.A not more near definable protective function opposite the micro caps during the production. 2. The Aktivi.erung of these reaction systems takes place via that the mechanical and/or physical forces the micro hollow bodies applied on the masses are broken and/or blown up to destroy and with the sharp-edged and spitzigen destruction products the micro cap walls developing thereby. Practice showed now that with such masses beeits a multiplicity of simplified application problems solvable and innovierbar are. However there are applications on the other side, in which sharp-edged and/or spitzige micro hollow body destruction products are hinderlich, because i0 changed them a) rough surfaces and/or b) final characteristics in the through-hardened and/or. supply with to durchvulkanißierten final products. This is valid in the special measure if the micro hollow bodies are to lend a low specific weight at the same time to the final product as filler. A goal of the invention is the supply of such improved single component masses, which contain inactivated reactants, which do not exhibit the managing disadvantages by reaction-preventing sleeves, as well as their production, activation and application. The task of the invention is solved daduch that the activatable 1-komponentigen masses, in those at least one the reaction partner, initiators and/or accelerator in, a reaction-preventing sleeve destroyable by mechanical and/or physical forces (n) is present, such micro hollow bodies contained, which are stable when applying mechanical and/or physical forces and supply no noticeable portion at destruction products. These sturdy micro hollow bodies are on the one hand according to invention “protective agents” during the production and storage of such masses and on the other hand with the application Schutzhül] ensprengmittel. Furthermore the sturdy micro hollow bodies are fillers, which lend low specific weights to the masses according to invention. The sturdy micro hollow bodies in accordance with the invention can be made of inorganic and/or organic materials. They preferably possess a hollow ball form. The inorganic micro hollow bodies can be e.g. manufactured among other things to the glass, blown and/or expanded mineral fillers,” lie fly ashes, pearlite, silicates, calcium, magnesium, boron silicates and such. The organic micro hollow bodies consist Aminound phenolic plastics of plastics, like thermosetting polymers, e.g. The cavity of the micro hollow bodies can if required e.g. being filled with inert gases, like nitrogen. The grain size of the sturdy micro hollow bodies can vary within wide limits and their diameters are < 3000 m, in particular < furthermore 1500 M. you possess low Schüttgewichte and low specific weights, which preferably < 1.0 g/cm3, in particular < 0.8 g/cm3, above all lower than the specific weight of the masses, in which they are contained. The auxiliary quantities of micro hollow bodies can vary likewise within wide limits and them lie preferably between 0,5 and 700 Gew. - % - related to the unfilled basis raw materials. The content of sturdy micro hollow bodies depends further on the content of micro caps, of the necessary protective function, dern filler content, the necessary sleeve blowing up capacity and the demanded characteristics of the final products. However should the according to invention microencapsulated materials containing single component masses at least one micro hollow body content between 1 and 100, preferably between 3 and 70 Gew. - % - related to the unfilled raw materials - exhibit. The masses according to invention can be developed on inorganic, metal-organic and/or organic basis. They can be present in liquid, pasty, thixotroper, semisolid and/or firm form. As inorganic monomers, oligomere and/or polymere connections are suitable among other things hydraulically tying masses, cements, like haven land, high alumina cement; Gypsum, anhydrite, magnesite, lime, silicates, like water glass. To the metal-organic systems among other things siliciumund/or titanium-organic connections, like Organosiloxane, belong silicone resins, Silikonkautsehuke, alkyl titanates. For the re-activatable single component masses on monomerer, oligomerer and/or polymere organic basis are suitable all reactive connections, which supply polyaddition reactions interlaced polymere and/or elastomers connections by polymerization, Polykondensationsund/or. Hiezu belong among other things vulcanizable natural and/or synthetic Kautschukund of elastomer systems, like butadiene acrylonitrile e {ischpolymerisate, butadiene styrene copolymers of polysulfides; To [nound phenolic plastics, IE Harnstoff~, Melamin Phenolund/or Resorcin aldehyde Kondens ate; Vinylund/or groups of serving containing connections, like Acrylund/or Methac ylsäure, their ester, amides, nitriles and their other derivatives, styrene and its derivatives, insatiated polyester resins; Epoxydverbindungen and Polyepoxyde, like aromatic, aliphatic and cyclo-aliphatic epoxy resins, Glycdidylester Glycidyläther; PU and other isocyanate-interlacable systems; Polyamine, PP, Polyimine, Polyimide and their derivatives and such. By the term “of the hardening serving component” are e.g. reaction initiators for the individual vulcanisation, polymerization, to thus understand Polykondensationsund/or polyaddition systems completely generally reactive connections which can initiate reactions. Hiezu belong to hardener, like e.g. polyamine, beside Coreaktanten among other things polyamide amines; admitted Radikalbildner, like peroxides, hydraulic peroxides, Persäure, their derivatives and salts; Oxidising agent, like lead dioxide, manganese dioxide; Isocyanates and their derivatives; Mercaptane and Mercaptoverbindungen. Furthermore fall under these components in accordance with the Erfin'dung also solvent, which by Anquellen and/or Anlösen can be used from physically tying systems to the reactivation of dry films. Among the reaction accelerators as the hardening serving component rank such connections, which can deliver easily electrons and take over thus tasks, like peroxide decay e.g. most accelerating. Hiezu belong above all to Schwermetallsalze, amines, amides, Imine, imides, MerZ0 captane, Azokörper and such Hiezu belong also to catalysts and such. Also aids belong here, if these materials remain inactive during the storage. Because they are to only lend during and/or after the application modifying characteristics to the masses. Such materials can among other things Konservierun£smittel, hydrophobic treatment materials, setting timers and/or masses, wetting agents, process means and such tying hydraulically accelerators for. z5 its. With the invention it becomes possible that under normal conditions not controllable expirations of reaction of highly reactive lugs e.g. due to short Topfund working times, by which temporarly effective sleeve inactivating formulierund becomes applizierbar. Thus Einkomponentensysteme can be manufactured among other things according to invention, which are re-activatable and harden also at temperatures under O°C. The re-activatable single component masses with a content microencapsulated reactive lugs on in accordance with the invention are in such a way developed that they remain inactive during the production and/or storage. Which of the reactive materials from a system are to be inactivated by sleeves temporarly, so that they can be under-mixed the other reactants, depends on the encapsulation technology, the kind of application and economy. Preferably such reactive materials in sleeves are present, which are contained in a system in smaller quantities. Therefore for some the re-activatable Einkomponentensysteme often the hardening causative component, preferably the reaction initiators and/or reaction accelerators, microencapsulates begun. The masses according to invention can be modified by further additives. Suitable additives are among other things softener, oils, tars, Asphalte, Bitumina, solvent, coloring materials, pigments, thixotropy means, inorganic and/or organic Fd1 lst0 ffe and fibers. Furthermore stabilizers and/or inhibitors can be added to them. According to invention the micro hollow bodies, Iviikrokapseln and/or fillers used in the masses can being additionally with bonding layers forming materials, like silanes, chrome complexes covered, in order among other things to achieve at the boundary surfaces intensified groups. They can being coated however for inactivating in relation to chemistry sorption procedures with lugs, like fatty acids, fatty acid esters or with frictionworth-improving materials, like fluorocarbons, graphite and such. For the production of the masses according to invention all are suitable the mixing units, which do not develop during the mixing process to high shearing stresses and/or frictions in the mixture property. Hiezu belong among other things to planet mixer, Trommelmischer, snail mixer. With the Hestellung of masses with high Viskositätsund/or thixotropy values, in particular if sharp-edged and/or spitzige filler particles are present, special care is necessary. It proved as very favourable, if the micro caps were moistened either before interfering with a liquid additive and/or oligomeren with liquid monomers, and/or trained polymere substances as the first component. Thereupon the additive of the micro hollow bodies has to take place. With the production and the following storage of the l-komponentigen masses according to invention the sturdy micro hollow bodies take over in particular then a protective function, how was surprisingly found, if their hollow body size is about same or larger than the average micro cap size. The protective function according to invention of the micro hollow bodies opposite the micro caps is based on that they work on the one hand as measuring rods and on the other hand than buffers and/or “adsorbent” in relation to the self-static forces, e.g. dead weight, in particular with high contents of specifically heavy fillers. To the protective function carries among other things. the stable hollow ball form and the low specific weight. The micro hollow bodies are simultaneous good sedimentation those and/or - timers into the 1-komponentigen according to invention masses, woduch additionally the accumulations by micro hollow caps to be prevented. This protective function according to invention of the micro hollow bodies with the production and storage of the 1-komponentigen according to invention masses shows alone a comparison with the use of glass beads in same size and same volume. The microspheres from glass possess Schüttgewichte from 1,3 to 2.5 g/cm3. With the employment of these microspheres already partial cap destruction enters and the withdrawn reactants and/or hardener already initiates polymerization procedures with mixing a mixing apparatus. The technical progress of this protective function according to invention is characterized additionally still thereby if in one, ho¢hreaktiven mass each high-filled with sharp-edged and spitzigen fillers only glass beads or only micro hollow bodies of same size and same percentages by volume are interfered in a so careful way that with this manipulation still no cap break develops. If these masses normal storage conditions are subjected, the following lets itself observe: The mass, which contains only Glaspelen, shows already after 12stündißer Laßerung hard polymerization nests and is through-hardened after 48 h. The mass with micro hollow bodies shows against it, as was surprisingly found, after 6monatiger storage unchanged rheologic characteristics, like by day the production. In an additional comparison the given deficiency in weight, which results from the different specific weights of the glass beads and micro hollow bodies, in the micro hollow bodies containing mass became balanced thereby as on the mass surface a stamp with the difference weight was put on. After 6monatiger storage no rheologic characteristic changes still polymerization nests were to be determined also at this mass. A further goal of the invention is a procedure for activating, hardnesses and/or accelerating of the l-komponentigen masses forwards, during and/or after the Applizieren. Hiebei transfer and loosen the sturdy micro hollow bodies a further task according to invention in the form that them with applying and/or in presence of mechanical and/or physical forces in the l-komponentigen masses as Mahlund/or friction bodies, similar to which, works meal principle of a ball mill. By this Mahlund friction procedure in the mass the sleeves are set blown up, the coated materials free, whereby the reaction is initiated. In order to create now high cap blowing up capacities, micro hollow body mixtures are preferably used, whose grain size spectra are adapted to those of the micro caps. The Aktivierungsverföhren is based essentially on that with applying and/or in presence of mechanical and/or physical forces the l-komponentigen masses are moved and the sturdy micro hollow bodies under this dynamics through meals and rubbing the sleeve walls to break and blow up. This predominating “ball mill effect” wid additionally by, hard and specifically heavy filler particles existing in the mass supports if necessary. The mechanical and/or physical forces can become among other things produced with pressure, shears, rotation and/or torsion. Thrust forces preferably result from presses, putties, stamping or striking. Shearing stresses preferably develop when agitating such masses in high-speed homogenisation machines, mills, Extrudern, kneading machines and such Rotations-und/or torsion loads are preferably predominating if the masses with pressures are shifted into a turbulent current or into the masses of elements with threads are pivoted. The activation is favoured and accelerated by the additionally developing frictions. Completely generally all mechanical destruction devices can support the activation functions according to invention de.r sturdy micro hollow body in the single component masses additionally, whereby it is guaranteed that a very high cap destruction ratio is reached. In order to lend unfilled or single component masses filled with soft fillers a sufficient activation capacity, are at least 5 Gew. - % at sturdy micro hollow bodies - related to the monomers, oligomere and/or polymere substance - necessary. Against it if additionally sharp-edged and/or spitzige Füllstoffpartikelchen is in the single component mass present and if a low activation capacity is demanded, is a minimum content of 1 Gew. - % to stable Mikrohohl10körpern - related to the monomers, oligomere and/or polymere substance - sufficient. A further goal of the invention is the use of the activatable single component masses according to invention in many ranges of the technology, the commercial economy, the handicraft, the do-it-yourself enthusiast and such. The activatable single component masses according to invention can be adapted to the respective specific processing technologies and/or intended purposes in their Zusammensetzun15gen, reactivities, activation barnesses, rheologic characteristics and technical values in ausund through-hardened condition. In addition, more universal re-activatable single component masses can be made available for several ranges of application. The Einkompönentenmassen according to invention is packaged in tubes, cartouches, doses, 20Hobbocks and such over several months storable. The masses according to invention can be used for sticking, detention, close, putty, filling, Stampf-und/or coat purposes. Furthermore the re-activatable single component masses according to invention for Modellund/or tool construction and for the production of pressing, Hohlund are suitable/or spraying bodies. The masses according to invention are developed among other things on the basis of thermosetting polymers, lie25fern its hardening by precipitation products relatively high mechanical strengtheningnesses, good Dimenslonsstabilitäten, relatively close structures and are preferably then machinable with Zerspanungswerkzeugen manually and by machine, if the micro hollow body portion is small highly and the content of hard, coarse-grained fillers. With the activatable single component masses according to invention a multiplicity of work-mad and/or substrates can interconnect and among themselves, seal, prime and/or cover. With the employment as $tampfund/oder insulating material cavities leave themselves, as holes, pipes and such to fill out. The materials and/or substrates know among other things metals, like steel, iron, aluminum, copper; inorganic materials, like stones, concrete, glass, ceramic(s); Elastomers; Plastics, like thermoplastics, thermosetting polymers; Holzund of timber materials; Plastic foils, plastic laminates; textile materials, paper, cardboard and such its. Such tasks for connecting, densities, putties, covering and/or filling are present in many technical ranges of the research, industry, the handicraft and the do-it-yourself enthusiasts. Hiezu belongs among other things construction industry with Hochund foundation engineering, as well as interior fittings; holzund kunststofverarbeitende industry, vehicle, Schiffsund aircraft construction, Maschinenund Apparate40bau, electro-technology, Modellund tool construction, furthermore many areas of the handicraft, like Elektround sanitary lnstallationen, assembly and repair sector and such. A special application sform the masses according to invention is the use as reakti. vierba, rer sticking, Dichtund/or priming off for Montageund/or repair purposes. Thus for example Befestigungsele #5 leave themselves mente, like screws, mooring rings, without additional mechanical means of mounting into boreholes to set and bond with such an adhesive according to invention. With the same masses however among other things also flange can be stuck together and sealed. o to a preferential application form in accordance with the invention belongs the employment by activatable single component masses in the cases of application, with which they are not additionally consolidated by noticeable destruction 50von micro hollow bodies, but also in hardened and/or out-vulcanized the condition the formulated, low maintain, specific weight. Hiezu belong for example adhesives, reaction resin mortar, sealants for the building industry, the automotive industry, as well as Klebeund screeding compounds. To a further preferential application form in accordance with the invention belongs the use of dry powder mixtures and/or laminates, which microencapsulated reactive materials, sturdy micro hollow bodies and/or other additives are activatable contained and by mechanical loads, like printing, shearing, Rotationsund/or torsion loads. The powder mixtures can being developed on inorganic basis, like cements, lime and/or on organic bonding agent basis. With the laminates it acts over organic polymers and/or bonding agents, which are processable under printing, vacuum and/or warmth for example. A further application form in accordance with this invention is the use of the activatable single component masses in Modellund tool construction. Hiefür are used among other things such 10Massen according to invention, which become machinable e.g. at ambient temperature a little vividly however at easily increased temperature, for example with hand deformation, knetund activatable and after their Durchhärtung with Zerspanungswerkzeugen. In addition, they are suitable for all other intended purposes, with whose technology such forces arise, which are sufficient for the activation of the sleeve explosives. A further preferential use of the re-activatable masses in accordance with the invention is the production of pressing, Hohlund/or spraying bodies. Thus for example other Duromeren and/or thermoplastic only suitable technologies, like Autoklavenmethod % printing vacuum method, are available pressure bag moulding, Kaltund hot-pressing techniques for processing the recktivierbaren single component masses according to invention in the range of the strengthened plastics, preferably the glass-fiber reinforced polyesters and, but by the vorgefertigen, liquid, p stösen, thixotropen, firm and/or powdery Einkomponentensysteme offer them as intermediate products molding compounds and/or prepreg a set of advantages. Such single component masses in accordance with the invention exhibit among other things homogeneous compositions, uniform reactivity, no Topfund working time and are storable several months. In the industrial technology, in the trade, Handwerksund He [mwerkerbereich there is a multiplicity of further ranges of application for the activatable single component masses in accordance with the invention, which cannot be discussed in detail. In accordance with the invention new and improved activatable single component masses are not only made available for many Anwendungsund of operational areas, which are not afflicted with the described and other disadvantages, but they exhibit a number of additional verarbeßtungsund application technology advantages, which are for a long time demanded on the part of practice. These advantages are in dependence of the respective single component mass the among other things following; forwards, during and/or after the processing re-activatable Einkomponentensystem with the well-known advantages Zweiund multi-component mass; easy and uncritical application, since no mixing of Zweioder is necessary multi-components; no mixture errors; easy and uniform activation barness; no Topfund working times; pre-programmed reactions, like Gelierund hardening times; non-sticking adjustable Verformungsund/or kneading characteristics; pumpable; adjustable permanent Viksositätsund/or thixotropy values; contraction-poor and/or contraction 0 free Ausund Durchhärten; Reduction or prevention of internal tensions and cracking; good Lagerstabilitäten of the masses; Decrease and/or removal of physiological and toxicological problems and/or environmental problems with the employment and processing dangerous working materials. The invention is described by the following examples more near, without however on it fuel element-+ 5 to be. The quantity specifications used in the examples and - conditions refer generally to the weight. Example 1: For the proof of the tasks of protective function according to invention of the micro hollow bodies with the production and storage of materials microencapsulated containing masses, masses according to table 1 were manufactured and the individual components in a planet mixer mixed homogeneous. The mixture ingredients No. 2 and 3 had in each case the adequate percentages by volume at glass beads and/or micro hollow bodies. The addition of the individual components took place in the indicated order.

The mixture ingredient 3 - in accordance with the invention - showed no change in its rheologic characteristics after 6monatiger storage and was perfectly processable and activatable. Example 2: A further mass according to invention with micro hollow body was specified compared with such with glass beads, in which the additives at micro hollow bodies and glass beads were added in each case in same volume parts, as in table 2.

Also this comparative stored points out that the tasks of protection transmitting clay/tone according to invention of the micro hollow bodies are characteristic opposite the glass beads in the l-komponentigen masses.

Both screeding compounds with a metal putty under normal putty printing i0 in as same a layer strength as possible on a degreased aluminum plate were up-primed by hand. In a 2nd examination the screeding compounds within an order framework in a strength were laid on from 80 to I00 m on degreased steel sheets. The screeding compound No. I, which contained sturdy according to invention micro hollow bodies, was in such a way angehärtet after 30 min both on Aluminiumals also on the steel sheet that the surfaces with Sandpapier were to be sharpened. The Sandpapier did not add itself thereby. After the screeding compound No. 1 on both surfaces was through-hardened further 10min. The screeding compound Nr.2 was still soft and plastic after 30 min on both surfaces and changed this condition even after further 120 min not. It was still soft after one day. The function according to invention of the sturdy micro hollow bodies is proven by this comparison as sleeve explosives, which work under mechanical and/or physical forces as Mahlund friction body. The microscopic investigations showed that the micro hollow bodies were not destroyed. Example 4: A sticking peg mass of the following composition was manufactured: I00 Gew. - Parts of Reakti¢nsharzlösung) Gew. - Parts of mikroverkapseltes N, N-Dimethyl-p-toluidin Gew. - Parts mikroverkapseltes peroxide, t0% Œ g, grain size: < 400 GM I0 Gew. - Parts of micro hollow body, grain size 20 to 70 m 265 Gew. - Parts of micro hollow body, grain size 70 to 250 m *) insatiated polyester resin, 60%ig in 1,3-Butandioldimethacrylat, viscosity about 1400 cP, acid number 24. This sticking peg mass was brought into a borehole made of concrete Bn 350, cleaned by drilling dust. The borehole had a screw depth of I0 D. Into the sticking peg mass bed a screw M I0 was deeply pivoted by means of drill press 8 D. After IO min could be solved and unscrewed the screw with a Losbrechmoment (LMB) from tons of Nm. A paßgeneues Gegengewinde was produced. Subsequently, the screw was again pivoted, tightened u.zw to D and with a torque (LMA) by t0 Nm. After 60 min could be solved the screw with a Losbrechmoment (LMB) from 50 Nm. Thus the Losbrechmoment (LMB) was appropriate for 25% over the torque (LMA) and fulfilled thereby more than the PraxisforderungenLMA > =l, two-way LMA. The borehole was vertically cut open and it could be determined perfect leads of thread, which were produced from the sticking peg mass according to invention. The microscopic investigations of the thread bars showed that no noticeable destruction of the sturdy micro hollow bodies had entered. Example 5: The following polysulfide sealants were manufactured in a planet mixer: Raw materials polysulfide polymers softener chalk titanium dioxide sulfur Thixotropiermittel Mikroverkapseltes lead dioxide 50 industrial union, in softener, grain size < 300 m micro hollow body, grain size: < 300 m number of revolutions the mixer witness mixture time seals measure of EN Nr.l Gew. - Parts of Nr.2 Gew. - Parts of I00 I00 0.2,0.2,3.8,3.8 Umdr/min 30 Umdr/min I0 min 10 min with the Diehtungsmasse No. 2 after the mixing process a weak brown colouring was observed, while the sealant No. I did not show this. This brown colouring is on a partial micro cap break, whereby lead dioxide flowed out as hardener to lead back. Both polysulfide sealants were pressed afterwards over a micro cap destruction device, which consisted of a chopper and a screw conveyor. The sealant No. I stepped homogeneous brown from the spraying nozzle and was through-hardened after about 90 min, while the sealant No. showed 2 only brown strips after activating and after 12 h still I0 was not through-hardened. The additive at sturdy micro hollow bodies in the sealant No. I demonstrates the strongly supporting sleeve explosive function to the same also in a micro cap destruction performing. Furthermore the sealant No. 2 shows that the mechanically working micro cap destruction devices do not fulfill the demands of practice until today yet. Example 6: In a planet mixer the following epoxy resin adhesives were manufactured: Raw materials epoxy resin micro cape seln*), grain size: < 200 m polyamide amine (hardener) micro hollow body, grain size: < 100 m number of revolutions the mixer witness mixture time adhesive Nr.l Gew. - Parts of Nr.2 Gew. - Parts of 120 I00 I00 Umdr/min min 120 I00 i00 Umdr/min min e) red dyed both adhesive mixtures were let stand 24 h. With adhesive No. 2 a viscosity rise and a weak Mikrokapselsedimentat on can be recognized after this period. The adhesive according to invention No. 1 did not show these features. Both adhesives on sand-radiated test sheet metals with an adhesive surface of I0 cm2 were then up-primed and ever 2 adhesive surfaces superimposed. After h8 h the adhesive No. I supplied a tension and shear resistance of 600 N/cmz, while the adhesive No. supplied 2 only such from 200 N/cmz. In the surface of fracture with adhesive of the No. 2 stuck together test sheet metals were still yield to determine not interlaced adhesive nests. The microscopic investigation resulted in that only about 50% the Epoxyd Mikrokapseln were destroyed. On the other hand the adhesive No. 1 had been fully activated by the content of micro hollow bodies. Example 7: A activatable Knetmasse was manufactured according to the following regulation: In a planet mixer, with a mixture speed of 50 Umdr/min, following components were merged: i0 i00 Gew. - Parts unsaturated polyester resin, 60%ig in Neopentylglykoldimethacrylat, Säurezahh 28, viscosity: 2700 cP Gew. - &lt parts sturdy micro hollow bodies; 70 m 2 Gew. - Parts magnesium oxide 3 Gew. - Parts grafting copolymers from PL and Methacrylsäure, Methacrylsäuregehalt: 15% Gew. - Parts colloidal silicic acid Gew. - &lt parts sturdy micro hollow bodies; 200 m I0 Gew. - Parts titanium dioxide I0 Gew. - Parts mikroverkapseltes peroxide, 40%ig, grain size: < 200 m this mixture dickte within 24 h so that a kneadable mass developed, which did not show surface tackness. If the Knetmasse between the fingers or on a Knetbrett was kneaded, then it was activated within 60 s by the kneading procedure. The activated mass was through-hardened after 12 h.
