908 Cold Galvanizing Long-Lasting Anti-Rust Anti-Corrosion Coating

Overview
Single-component cold galvanizing zinc-rich anti-rust anti-corrosion coating for steel structures, used as a primer where thermal spray zinc is not convenient.​

Composition
Polyolefin resin, ultra-fine zinc powder, light-colored composite anti-rust pigments, additives, solvent.​

Typical uses
Anti-corrosion primer for steel structures, especially where thermal spray zinc is not practical.​
