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 a resin composition consisting of an epoxy resin and a polyvinyl butyral, an oxyacid salt or a metal oxide, and a flaky pigment or aggregate.

CONSTITUTION: The titled composition consists of 100pts.wt. resin composition (A) consisting of 99W60wt% epoxy resin (e.g. a linear bisphenol type epoxy resin, polyphenol type epoxy resin) containing two or more epoxy groups at the terminals and 1W40wt% polyvinyl butyral (e.g. the one having an average degree of polymerization of 250W2,000 and a degree of butyralation of 57W75mol%), 1W250pts.wt. compound (B) selected from an oxyacid salt (e.g. zinc phosphate, lead chromate) and a metal oxide 9e.g. chromium trioxide) and 10W500pts.wt. constitutent (C) selected from a flaky pigment (e.g. flaky iron oxide, flaky aluminum powder, mica) and an aggregate (e.g. sand, silica sand).
