2K epoxy anti-corrosive primer that chemically reacts with surface corrosion to form a stable protective complex. Applies directly to corroded steel up to 60µm, minimizing surface preparation. Minimum 40µm DFT, universal topcoat compatibility.
PLH53-5 Epoxy Rust-Tolerant Anti-Rust Primer is a two-component, polyamide-cured epoxy rust-tolerant anti-rust primer designed for application on slightly rusted steel surfaces and incompletely cleaned metal surfaces.
The product is formulated with epoxy resin, active anti-rust pigments, organic nitrogen base, penetrant, stabilizer, additives, and solvent, and is supplied with a polyamide curing agent as Part A and Part B. The coating film is described as forming stable complexation with the substrate before hardening to stabilize rust and provide durable rust protection.
Designed for application on slightly rusted steel surfaces
Suitable for incompletely cleaned metal surfaces
Minimum surface preparation is stated as St1/St2
Described as stabilizing rust before hardening
Can be applied by airless spray, brush, or roller
Compatible with a wide range of intermediate coatings and topcoats
This primer is suitable for steel protection projects where rust-tolerant application and simplified surface preparation are required.
Typical application areas
Slightly rusted steel surfaces
Incompletely cleaned metal surfaces
Steel substrates requiring anti-rust priming
Maintenance and repair uses
Direct application on slightly rusted steel
Direct application on incompletely derusted metal surfaces
Remove oil, loose dust, water stains, and loose rust; minimum surface preparation St1/St2; surface profile 15–35 µm. If derusting is more thorough, performance is stated to be more prominent.
Storage
Store in a dry, cool, ventilated warehouse away from fire sources and direct sunlight; outdoor storage is not permitted.
This primer is compatible with epoxy MIO intermediate coating, epoxy topcoat, polyurethane topcoat, acrylic topcoat, chlorinated rubber topcoat, high chlorinated polyethylene topcoat, chlorosulfonated polyethylene topcoat, and chlorinated ether topcoat.
