High-build Epoxy Zinc Phosphate Primer (Grey, Iron Red)
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 paintcontains 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 primerdoes 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 oxideare 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 aluminumhave slightly lower substrates requirements than zinc phosphate primer greyand 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.
