PURPOSE: To provide the titled compsn. capable of forming a tough coating film having excellent corrosionproofness against articles to be coated (particularly steel), by blending a specified epoxy resin-modified unsaturated polyester resin, glass flake and a flat metallic flake pigment. n CONSTITUTION: An epoxy resin-modified unsaturated polyester resin obtd. by bonding an unsaturated polyester having aryl ether and carboxyl groups [e.g. a partially esterified product between maleic acid (anhydride) and glycerol monoaryl ether] to the epoxy group of a bifunctional bisphenol A type epoxy resin having an epoxy equivalent of 100W500, is used. 100pts.wt. said resin, 10W 70pts.wt. glass flake having an average thickness of 0.5W10μ and an average size of 100W400μ and 10W150pts.wt. flat metallic flake pigment (e.g. flat zinc powder having an average thickness of 3W10μ and an average length of 30W 300μ) are blended together. n COPYRIGHT: (C)1984,JPO&Japio |
