Abstract
PURPOSE: To prepare a thermosetting powder coating composition of high pigment concentration, by adding a polybasic carboxylic acid crosslinking agent to a mixture of a copolymer of a glycidyl group-containing monomer and an ethylenic unsaturated monomer, and pigment, and again heating and kneading the resulting mixture.
CONSTITUTION: A copolymer having a number average molecular weight of 1500W 30000 and a glass transition point of 5W80°C prepared by the copolymerization of (a) 5W40 wt% of a monomer containing a glycidyl group or a methylglycidyl group with (b) 95W60 wt% of other ethylenic unsaturated monomer, is heated at a temperature to attain the melt viscosity of the copolymer of ≤500 poise, and kneaded with pigment. The mixture thus obtained is molten and kneaded with a polybasic acid crosslinking agent and if necessary, with the additional amount of the above copolymer.
