PURPOSE: To obtain a paint composition for a power transmission iron tower plated with zinc, which paint composition is excellent in the adherence and non- slip characteristics, by making up the composition of an epoxy resin composition, an oxyacid salt or a metal oxide, and a flaky pigment or aggregate.

CONSTITUTION: The titled composition consists of 100pts.wt. epoxy resin composition (e.g., a linear or branched bisphenol type epoxy resin) (A) containing two or more epoxy groups at the terminas and one or more hydroxyl groups in the side chain, 1W250pts.wt. compound (B) selected from an oxyacid salt (e.g. zinc phosphate, lead chromate) and a metal oxide (e.g. chrominum trioxide) and 10W500pts.wt. constituent (C) selected from a flaky pigment (e.g. flaky iron oxide, flaky aluminum powder, mica) and an aggregate (e.g. sand, silica sand). If 10W200pts.wt. metal zinc powder and/or calcium plumbate are further added, the long-term adhesion of its coating can further be stabilized and prolonged.
