Functions and Uses：
1. ZRT-955 is an environmental-compliant solution and it’s free of phosphorus, free of nitrogen, and free of heavy metals. It is a new innovation to replace the phosphate coating.
2. ZRT-955 can deposit a Nano-film on the surface of metal, which can improve the adhesion and Anti-Tarnish of the metal to the vanish paints.
