Abstract

1381023 Powder lacquering RUTGERSWERKE AG 25 May 1972 [27 July 1971] 24778/72 Heading C3R A powder lacquering process comprises applying a particulate unsaturated branched-chain polyester having a hydroxyl number of from 30 to 110 to a substrate and fusing to form a coating on the substrate, the polyester being derived from a dicarboxylic acid and an alcohol component consisting of 75 to 97 mol per cent of a diol and 25 to 3 mol per cent of a polyol having at least three hydroxyl groups, at least one of the polyester reactants being unsaturated. The polyester preferably has an acid number of from 5 to 40. The examples describe unsaturated polyesters prepared from (a) dimethyl terephthalate, 1,4-butanediol or ethylene glycol, trimethylol propane and fumaric acid, (b) ethylene glycol, dimethyl terephthalate, fumaric acid, trimethylolpropane, phthalic anhydride or adipic acid and 2,2-dimethylpropan-1,3-diol, and (c) ethylene glycol, pentaerythritol and fumaric acid, which may be mixed with titanium dioxide powder, ground to the required particle size and sprayed on to degreased steel plates and beechwood plates.
