Silicia Particles Containing Trivalent Passivate for Zinc and Zinc Alloy
LANTHANE TR-175 passivate is a unique and highly protective post-plating treatment system for zinc and zinc alloy electrodeposits.
It polishes, brightens and passivates zinc surfaces via the same chemical reactions that take place in hexavalent chromates, but is Chrome IV-free. Instead, it’s based on trivalent chrome compounds that are used in combination with nano-particle technology.
The colour of the film varies slightly, depending upon the type of deposit over which it is applied. Alkaline non-cyanide zinc deposits typically exhibit a slight pearlescent appearance. Chloride zinc deposits generally exhibit a clear, white appearance. Zinc/iron deposits typically have a more pronounced iridescent appearance. In all these instances, the film formed can provide 240 to 350 hours of salt spray protection to the first appearance of white rust.
