Permeable surface treatment coating

The basic principle of permeable surface treatment coating is to use a resin with strong permeability, combined with polar solvent and penetrant to make the coating have good performance and enhance the adhesion of the coating.


Stable surface treatment coating

The basic principle of stable surface treatment coating is mainly based on the active materials in the coating react with the active ingredients in the rust layer. The more active materials used are zinc oxide, zinc phosphate, zinc chromate, barium chromate, organic nitrogen alkali chromium Acid salt, calcium chromate, aluminum tripolyphosphate, some formulas also add sodium nitrite, and some think that the addition of strontium chromate is necessary.


Conversion surface treatment coating

Conversion surface treatment coatings are also called reactive rusty coatings. These coatings do not contain film-forming substances. Because of this, additional primers are needed. If they contain film-forming substances, they are called rust conversion primers.
