1320800 Coating a substrate GLASURITWERKE M WINKELMANN AG 18 Dec 1970 [24 Dec 1969] 60250/70 Heading B2E [Also in Division C3] A coating on a substrate is produced by depositing a film of liquid coating material on the substrate, which material comprises synthetic resin material either consisting of an unsaturated polyester and a copolymerisable monomer containing a peroxide catalyst, an accelerator, and an opaque filler or pigment, or consisting of a condensation resin, an acid accelerator or a polyisocyanate hardener, and an opaque filler or pigment; and subjecting the film to electromagnetic radiation produced by a high pressure mercury vapour lamp. In the Examples coating materials comprising an unsaturated polyester resin dissolved in styrene, titanium dioxide, toluene, nitrocellulose dissolved in butyl acetate, cobalt naphthenate, tertiary butyl peroctoate, benzoin isopropyl ether, methyl glycol, cyclohexanone peroxide, a middle oil alkyd resin solution in xylene modified with soya oil, a urea formaldehyde resin dissolved in butanol/xylene, a bentonite reacted with a quaternary ammonium compound, wax paste, silicone oil solution, para toluene sulphonic acid, an alkyd resin in xylene modified with non-drying vegetable fatty acids, matting medium and a polyfunctional aromatic-aliphatic isocyanate are coated into chipboard and irradiated with high and low pressure mercury vapour lamp.
