This product is a two-component epoxy anti-rust paint composed of epoxy resin, zinc phosphate and titanium dioxide or iron oxide red and other pollution-free anti-rust pigments and polyamide curing agents, mainly used as a primer for fireproof coatings and primer for steel surface and pipeline anticorrosion.

Advantage OF high build zinc phosphate primer (Grey, Iron Red)
The membrane has good water resistance and salt water resistance

The paint film is tough and has excellent adhesion and impact resistance

The paint film has good oil resistance and solvent resistance

It has good matching performance with epoxy, epoxy asphalt and polyurethane topcoats, and has good interlayer adhesion

The use of pollution-free anti-rust pigments is beneficial to environmental protection

The paint film has good anti-rust performance and durability

What is the difference between epoxy zinc rich primer and epoxy zinc phosphate primer?
The difference between epoxy zinc-rich primer and epoxy zinc-phosphate primer is mainly due to their different anti-rust effect. Epoxy zinc rich primer is mainly based on electrochemical anti-rust effect with corrosion protection effect, while epoxy zinc phosphate primer is mainly based on corrosion inhibition effect with shielding effect.

Rust protection is different

The china zinc phosphate paint contains zinc powder, and the content of zinc powder in the dry film is about 60-80%. Its anti-rust effect is mainly reflected in the electrochemical anti-rust aspect, that is, zinc powder is corroded before steel, and substances with corrosion-inhibiting effect are produced to continue to protect steel from rust.

High build phosphate quick dry primer does not contain zinc powder. It has excellent corrosion inhibition and shielding effect. It can prevent rust by corrosion inhibition and water vapor infiltration.

Usage is different

Epoxy zinc phosphate primer red oxide are used for sandblasting and derusting of steel structures used in atmospheric environments, especially coastal, humid outdoor environments, and equipment and facilities that require a long anticorrosion period.

epoxy zinc phosphate primer aluminum have slightly lower substrates requirements than zinc phosphate primer grey and are used for general mechanical equipment, outdoor corrosion-resistant coatings of steel structures up to 7 years, as well as for various indoor steel structures.
