Type CG Cold Galvanize is an industrial aerosol coating for metal protection and repair. Powerful CG contains 95% pure zinc; when sprayed on metal it forms a zinc-rich coating that prevents rust and inhibits corrosion through sacrificial galvanic action. Type CG aerosol offers easy on-the-job application, and is ideal as a primer or for touch-up. Quick drying CG contains no chlorinated solvents, and is excellent for weld coating.
