Strontium phosphate yellow combines with the metal surface to form stable chelates. It has excellent adhesion and anti-corrosion properties for metal substrates, especially for aluminum alloy, aluminum-magnesium alloy and galvanized sheet surfaces.
It achieves the purpose of rust prevention by changing the properties of the surface through chemical reactions or the characteristics of reaction products, and has a good enhancing effect on the salt spray resistance of light metal coatings.
The main function is to prevent metal corrosion, improve the protective effect of the paint film on the metal surface, and effectively increase the resistance of the coating to media.
