HA metal deactivators

HA metal deactivators This passivating agents for a variety of metal passivation rust, dense transparent passivation film, to retain the original appearance of the metallic color, conductivity and weldability. As aluminum, copper, zinc, iron and long-term passive antirust, without prejudice to the properties of the surface coating. As a high corrosion resistance metal passivation rust-proof, such as: Zinc Alloy copper-tin, nickel, nickel-phosphorous alloy, stainless steel, zinc alloy wire, aluminum wire, zinc alloy stampings, aluminum stampings. Can improve the corrosion resistance of 5 to 10 times. As zinc and zinc alloy passivation agent, aluminum and aluminum passivating agent can maintain resistance to neutral salt spray test more than 120 hours. Zinc and zinc alloy passivation film may be colorless, but also for color.
