Product performance: Slightly soluble in water, easily decomposes when exposed to strong acid or alkali. Has good anti-rust properties.

Main applications: It can be used for alkyd primer, phenolic primer, perchlorethylene primer, epoxy resin primer, polyurethane primer, etc. It is mainly used for phosphating primers. Its high content of zinc salt can participate in the reaction of vinyl butyral phosphate, and the complex formed can passivate the metal surface well and improve its adhesion. It can also be used for anti-corrosion of light metal surfaces in aerospace equipment. It is an excellent anti-rust pigment for light metals.
