Abstract
A method of inhibiting a base metal from rusting which comprises applying to the metallic base a thermosetting fluororesin powder coating composition containing substantially no chlorine. Thus, the metallic base can be effectively prevented from rusting. This method is especially useful for coating in coastal regions where salt damage is a problem, in the outdoors where acid rain causes damage, and in kitchens.
Claims5
A method of inhibiting rusting of a metallic substrate by coating the metallic substrate with a thermosetting fluorine-containing resin powder coating composition which has a glass transition temperature of from 45° to 120°°C. and does not contain essentially chlorine atom.
