Product introduction: The chromium free passivating agent for stainless steel is composed of environment-friendly inorganic acid as the main oxidant, high efficiency anode adsorption intermediate auxiliary, corrosion inhibitor and a small amount of macromolecular passivation accelerator. It is acid free, chromium free, non-toxic, tasteless and can be used at room temperature. Passivation of this product can effectively ensure that the original color of the workpiece will not be damaged, the size of the workpiece will not be changed, and the salt spray resistance of stainless steel workpiece will be greatly improved.

 

Product features:

 

1. Environmental protection characteristics: the product is environmentally friendly, with super passivation capacity, and the working fluid can be biodegradable;

 

2. Performance advantages: after passivation, the neutral salt spray of stainless iron can last for 48-72 hours, that of 303 stainless steel 48-96 hours, and that of 304 and 316 series stainless steel can last for more than 1000 hours;

 

3. Film forming characteristics: improve the high brightness of the stainless steel surface, and the film surface has anti fouling effect;
