Zink Rich Paint

Zinc powder is the most important electrochemical antirust pigment. Zinc-rich paint is divided into an inorganic zinc-rich primer with silicate as binder and epoxy zinc-rich primer with epoxy resin as a binder.

Zinc can be melted and purified into fine particles of high-purity zinc powder, which is used as the most important anti-rust pigment in anti-rust paint. Zinc-rich paint is widely used in various constructions and is suitable for offshore installations, power plants, petrochemical plants and other aspects. Zinc-rich paints are available in two types , first is organic ,which consist of epoxy resins, chlorinated hydrocarbons and other polymers; and second as inorganic based on organic alkyl silicates.

The performance of organic zinc-rich coatings depends on the solvent system. Coatings rich in organic zinc have a high temperature resistance of 200-300 F, The inorganic zinc-rich coating, adhering to steel with good chemical reactivity, has good solvent resistance, and can withstand temperatures up to about 700℉(375℃). Inorganic zinc-rich coatings are not easily crushed, peeled or blistered.
