Product Details

Product Description

Anti corrosion coating is an integrated system from primer to top coating, and primer is the base of the whole system that plays an important role for the coating quality. Primer has two major functions: first, infiltrate into substrate and steady the residual particles strengthen the base and avoid air and moisture penetration, and then second is to form a good supporting system with the following layers then increase the adhesive strength to the substrate.


Coating is dense, tough, full bright, colorful without yellowing and pulverization, anti-aging, with excellent weather resistance luster and color retention and decoration.
