A WATERBORNE ANTICORROSION COATING COMPOSITION AND PROCESS FOR PROVIDING A CORROSION-RESISTANT COATING ON A METAL SURFACE.

摘要

A waterborne coating composition, a process for providing a corrosion-resistant coating on a corrodible metal surface, an anticorrosion film formed by the composition, as well as an anticorrosive article, are disclosed. The coating composition comprises 10-35% by weight of one or more fluoropolymer; 30-65% by weight of one or more phenoxy resin; one or more crosslinking agent; a liquid carrier medium; and 0-40% by weight of an auxiliary binder consisting of one or more of polyethersulfone, polyphenylene sulfide, polyamide, polyimide, polyamideimide, polyether ether ketone, polyetherimide, polyurethane, alkyd resin, polyester, or acrylic polymers.
