Product Details

J-4 stainless steel passivation spray :After the metal has been oxidized by the oxidizing medium, its corrosion rate is significantly lower than the untreated before.

Product Description

1.The passivation mechanism of stainless steel passivation solution J-4 is mainly explained by film theory.It is believed that passivation is due to the fact that the metal reacts action with the oxidizing medium then forms a very thin, dense, well-covered, passivating film that can be strongly attached to the metal surface.This layer of film is present independently, usually oxygen and metal compounds.It plays the role of metal compeletely sepreated from corrosive media and prevent contact each other directly.

2.So that the metal basically stopped dissolving to form a passive state to achieve the effect of preventing corrosion.
