Chromium-free Passivation Additive
LW-19 chromium-free passivation additive is a kind of colorless transparent and environmental protection additive. It applies the composite salts to form the uniform chemical conversion film on aluminum surface which can effectively enhance the coating film adhesion and corrosion resistance to the surface and the coating. LW-19 is chromium-free and in line with the green environmental protection requirements, can completely replace the traditional chromium passivation coating for aluminum surface treatment, it can also be used to spray or immersion.
