Process of coating metals prior to cold forming |
摘要 |
A process of forming on a metal substrate a composition prior to the substrate being cold worked. The process includes a step of contacting the substrate with an aqueous composition comprising acid-stable particles and one or more fluoroacids. The amount of the acid-stable particles in the coating composition is from 0.005% to 8% by weight on a dry weight basis.
