Overview
Two-component vinyl phosphating primer formulated to form a coating with chemical adhesion on non-ferrous/light metal surfaces and improve adhesion of subsequent coatings.​
It is used for phosphating treatment on galvanized steel and aluminum; when used with epoxy anti-rust coatings, it is stated to enhance salt spray corrosion resistance and moisture resistance of the coating film.​

Composition
Polyvinyl butyral resin, anti-rust pigments, passivator, solvent, additives; acidified curing agent.​

Typical uses

• Phosphating treatment primer for galvanized steel, aluminum, and other light metal substrates to improve intercoat adhesion of subsequent coatings.​
