UV-curable surface-coating systems

UV-curable surface-coating (paint, lacquer, enamel) systems are proposed which, in addition to a UV-curable constituent, contain a two-component constituent. The UV-curable constituent comprises one or more prepolymers, one or more reactive thinners and a photoinitiator or an initiator mixture, and the two-component constituent comprises one or more epoxy resins and one or more amide curing agents or one or more polyols and one or more isocyanic curing agents. These surface-coating systems are distinguished by the fact that they require only very short curing times, consume little energy during curing, and are environmentally friendly. They are also and in particular suitable for heat-sensitive parts. In addition, a wide range of starting materials can be employed for these surface-coating materials, so that a very considerable degree of freedom is available with respect to properties and colour of the surface-coating film produced.

Radiation curable coating

A radiation curable coating composition for various substrates containing an adduct of acrylic acid and an epoxy resin (which may be modified with an anhydride, such as maleic anhydride), and a reactive acrylate monomer vehicle. The coating composition can be pigmented and can also contain additives commonly used in coatings, such as wetting agents and flow control agents. The coating composition does not require the usual hydrocarbon vehicles that give rise to air pollution problems. Surface gloss of a UV cured film obtained from a pigmented coating composition can be increased by using a photosensitizer combination of 2-chlorothioxanthone and a phenyl ketone, such as benzophenone. Adhesion of a cured coating is improved by replacing the tertiary amine co-sensitizer, at least in part, with dimethylaminoethyl acrylate.

A coating composition which is suitable for the production of photopolymerisable coatings on contact wafers for solder masks, contains the following: a) an ethylenically unsaturated, polymerisable reaction product of an aromatic polyepoxide and an ethylenically unsaturated carboxylic acid. The product is solid or semisolid. b) An inert, inorganic filler. The filler and the reaction product (a) are present in a weight ratio of from 20 to 65 parts of filler to from 80 to 35 parts of reaction product. c) A photopolymerisation initiator for the polymerisable reaction product, and d) a volatile organic solvent for the polymerisable reaction product.

They are allowed to dry by evaporation of the organic solvent in order to give, on the substrate, a photopolymerisable coating which can be treated by actinic radiation, for example through a template pattern. The material treated in this way is insensitive to hot soldering and is accordingly suitable as a solder mask in the production of printed circuits.

Radiation curable coating

RADIATION CURABLE COATING ABSTRACT OF THE DISCLOSURE A radiation curable coating composition for various substrates contains an adduct of acrylic acid and an epoxy resin (which may be modified with an anhydride, such as maleic anhydride), and a reactive acrylate monomer vehicle. The coating composition can be pigmented and can also contain additives commonly used in coatings, such as wetting agents and flow control agents. The coating composition does not require the usual hydrocarbon vehicles that give rise to air pollution problems. Surface gloss of a UV cured film obtained from a pigmented coating composition can be increased by using a photosensitizer combination of 2-chlorothioxanihone and a phenylketone, such as benzophenone. Adhesion of a cured coating is improved by replacing the tertiary amine co-sensitizer, at least in part, with dimethylaminoethyl acrylate.
