Catalysis of epoxy resin formulations having sparingly soluble catalysts

The present invention relates to epoxy resin formulations having a specific sparingly soluble catalyst mixture for enhancing reactivity.

Blocked polyisocyanates, process for their preparation, and coating materials and coating systems produced therefrom

Disclosed are blocked polyisocyanates having a free NCO content of less than 2% by weight in which the NCO groups are blocked with .alpha.-hydroxycarboxylic acid esters of the general formula: (I) (in which R1 and R2 are each hydrogen, alkyl, alkenyl, aralkyl or aryl group and R3 is alkyl, alkenyl, aralkyl or aryl group). The blocked polyisocyanates are useful as adhesive or coating materials.

Process for manufacturing surface-sealed hollow glass containers

A process for manufacturing surface-sealed hollow glass containers is characterised in that during the manufacturing process the hollow glass containers are coated with a water-based, silane-containing cold treatment product at the outlet area of the cooling furnace arranged after a machine for manufacturing hollow glass containers, and in that a second layer of a water-based cold treatment product which contains the following components is applied on said first layer: (I) a water-based organopolysiloxane-containing composition produced from alkoxysilanes bearing a functional group and alkoxysilanes selected among trialkoxysilanes, dialkoxysilanes and tetra-alkoxysilanes; and (II) a silicium-free component selected among waxes, partial fatty acid esters, fatty acids and/or surfactants. The thus produced hollow glass containers have an increased continued use resistance.

Polyurethane compounds containing hydroxyl terminated uretdione groups

The invention relates to specific polyurethane compounds containing hydroxyl terminated uretdione groups for use in the plastic field.

Cross-linking agents and thermosetting lacquers

Disclosed are novel cross-linking agents, which when reacted with thermosetting resins such as polyester polyols, improve mechanical characteristics such as resistance to scratching, acid, and crystallization. The cross-linking agents are formed from (A) an aliphatic or cycloaliphatic polyisocyanate having 2-6 free isocyanate groups, (B) a secondary 3-aminopropyltrialkoxysilane and (C) another blocking agent.

Processo para a preparacao de recipientes ocos em vidro de superficie selada com elevada resistencia de utilizacao

Process for producing surface-sealed hollow glass containers having a high use strength

A process for producing surface-sealed hollow glass containers, the hollow glass containers are, in the production process in the region of the exit from the annealing lehr which is located downstream of a machine for producing hollow glass containers, coated by means of a water-based cold end coating composition comprising at least the following components:I. a trialkoxysilane, a dialkoxysilane and/or a tetralkoxysilane or their hydrolysis and/or condensation products and alsoII. a water-soluble or water-dispersible mixture of a polyol and a crosslinker,wherein the applied layer of the cold end coating composition is subsequently subjected to a crosslinking step. The hollow glass containers produced in this way have an improved strength.
