LW-19 Chromium free Passivation Additive is a remarkable product in the field of metal surface treatment. As a passivation agent, it stands out for its unique properties and environmental friendliness. It is a colorless transparent and eco-friendly additive, also known as a Silane ceramic film forming agent or anti-corrosion additive. In the context of aluminum surface treatment, LW-19 serves as a Powder Coating Agent. It utilizes composite salts to create a uniform chemical conversion film on the aluminum surface. This not only effectively enhances the adhesion of the coating film but also significantly boosts the corrosion resistance of both the surface and the coating. It is completely chromium-free, fully complying with green environmental protection requirements, and can perfectly substitute traditional chromium passivation coatings for aluminum. When it comes to the Aluminium Anodizing Process, LW-19 can play an important supplementary role. Although it is mainly a passivation a…
