Zinc Rich Steel Rust Inhibitive Primer

STEELZ™ ZR is a high-performance, two-component metal primer formulated as a moisture-cured polyurethane zinc-rich coating. Engineered for superior adhesion and corrosion protection, this surface-tolerant primer can be applied over dry abrasive-blasted or power-tool-cleaned steel substrates—even on sound, tightly adherent rusty steel. Its fast-cure technology allows same-day recoating, making it ideal for demanding industrial environments.

Features & Benefits

• Rusted steel and prevention coating – Protects and restores steel surfaces
• Excellent wetting out and adhesion to sound rusty steel – Ensures strong bond for long-term durability
• Moisture-cured polyurethane zinc-rich primer can be applied to dry abrasive blasted or power tool cleaned steel – Versatile application for challenging conditions
• Excellent adhesion over sound tightly adherent rusty steel surfaces – Maintains integrity even on imperfect substrates
• Provides galvanic protection to carbon steel surfaces and is resistant to creeping, undercutting, and blistering – Superior corrosion resistance
• Superior to epoxy primers – Outperforms traditional coatings for longevity and protection
• Can be top-coated with epoxies and urethanes – Flexible finishing options for enhanced performance

Perfect For

• Industrial steel structures exposed to harsh environments
• Maintenance and repair of rusted steel surfaces
• Applications requiring fast recoating and long-term corrosion protection
