Explanation

Also known as zinc yellow. The main component is zinc chromate, light yellow or medium yellow powder, with relative density of 3.9. The chemical composition may vary depending on the formula and production process. Products without K2O have large oil absorption, weak coloring power and covering power; On the contrary, bright colors have less oil absorption. The light resistance increases with increasing content. tinting strength and covering power are lower than chrome yellow, but light fastness is better. It can be slightly soluble in water and completely soluble in acids or alkalis. It has the function of anodic protection passivation and cathodic corrosion inhibitor, and is an important anticorrosive pigment. Zince chrome is mainly used to prepare various anti rust primer, and can also be made into zinc yellow perchloroethylene primer, zinc yellow epoxy ester primer, zinc yellow polyurethime primer, etc.
