Theoretical Amount and Coverage Calculation of Inorganic Zinc-Rich Primer

Inorganic rich zinc primer is a member of the zinc primer family, which, like epoxy rich zinc primer, relies on the electrochemical action of zinc content to achieve good anti-corrosion effect on metal surfaces. The anti-corrosion effect of inorganic rich zinc primer is similar to that of epoxy rich zinc primer, and it dries quickly and can be cured at low temperatures. Today, let's understand the theoretical dosage and coverage area of inorganic rich zinc primer.

Dosage of inorganic rich zinc primer

Theoretical dosage: The theoretical dosage of inorganic rich zinc primer varies depending on the model and brand.

Our company's product, inorganic rich zinc primer, has a specific gravity of 1.8kg/L. During construction, the dry film thickness is generally around 80μm, and the dry film can reach 40μm. Under this premise, the theoretical dosage of inorganic rich zinc primer is 330g/㎡.

With the same film thickness, the dosage differs, which is fundamentally related to the solid content of the paint. The higher the solid content, the higher the theoretical dosage and the better the corrosion resistance. The solid content of inorganic rich zinc primer is the zinc content. The higher the zinc content, the stronger the corrosion and rust resistance of inorganic rich zinc primer.

Application of inorganic rich zinc primer

Inorganic rich zinc primer is generally used on the surface of metal steel structures and requires the surface of the metal to be polished and cleaned to sa2.5 level.

Attention should be paid to humidity during construction. Inorganic rich zinc primer is wet cured and requires the film to be moist.

Matching of inorganic rich zinc primer

Inorganic rich zinc primer can be matched with a variety of topcoats, such as epoxy paint, chlorinated rubber paint, fluorocarbon paint, etc., according to specific conditions.

The reason why the theoretical dosage of inorganic rich zinc primer varies among different manufacturers and brands lies mainly in the difference in zinc content. If higher anti-corrosion requirements are needed, choose paint with a higher zinc content.

Choose inorganic rich zinc primer with different zinc content based on specific needs. If you have any questions, feel free to ask us.
