Abstract
1450414 Powder coating compositions BRIGGS & TOWNSEND Ltd 20 June 1974 [21 June 1973] 29634/73 Heading C3R Powder coating compositions comprise the reaction product of a hydroxyterminated polyester with a partially blocked di- or poly-isoeyanate having from 0À5 to 1À2 free isocyanate groups, the blocking agent being selected from cyclohexanol, linear or branched chain aliphatic alcohols and oximes and the amount of partially blocked isocyanate being such that in the resultant composition there are 0À5 to 1À4 blocked isocyanate groups for each remaining free hydroxyl group of the polyester. The powder coating may be applied to a substrate and cured by heating at a temperature of 120‹ to 250‹ C. In an example a polyester derived from isophthalic acid, phthalic anhydride, adipic acid, neopentyl glycol and trimethylol propane is reacted with toluene diisocyanate which has been partially blocked with cyclohexanol to produce a powder coating which is coated on to a metal substrate and cured by heating.
