Rust-oleum 9807370 Dtm Urethane Mastic Coating 5 Gallon

Product Description

The RUST-OLEUM 9807370 is a 5-gallon container of High Performance 9800 System DTM Urethane Mastic, a two-component direct-to-metal (DTM) topcoat engineered for moderate to severe industrial environments. This high-solids, high-build coating delivers exceptional corrosion resistance and long-lasting color retention without requiring a separate primer coat on properly prepared metal substrates. The masstone gloss finish resists sag during application and cures to an extremely durable surface. Industrial painters and maintenance coatings contractors apply this product to tanks, towers, structural steel, and metal equipment where aggressive exposure conditions demand maximum protection. The base component is ordered separately from the activator.

This coating is suited for industrial and commercial maintenance projects where direct-to-metal application on tanks, towers, and metal equipment is required. It performs in aggressive environments including chemical exposure, weathering, and high-humidity conditions. The formulation meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities, making it appropriate for food processing and agricultural facility applications. For best results on bare or marginally prepared metal, prime first with the HS9300 System Epoxy Primer in red or gray before applying this topcoat.

Key Features

• Direct-to-metal (DTM) formula — self-priming on properly prepared surfaces, covers in one coat
• Two-component urethane mastic system — base and activator ordered separately
• High-solids, high-build, sag-resistant formulation for aggressive industrial settings
• Two-year rust-proof guarantee with maximum corrosion resistance
• Meets USDA requirements for incidental food contact; accepted in federally registered Canadian food facilities
• Masstone gloss finish with durable color retention in severe environments

Compatibility

Designed for use on tanks, towers, metal equipment, and structural steel in moderate to severe industrial environments. Compatible with the HS9300 System Epoxy Primer as a recommended primer coat. This is a two-component product — base (9807370) and activator must both be ordered to complete the system.

Installation Notes

Application should be performed by qualified industrial coatings painters or maintenance professionals familiar with two-component urethane systems. Surface preparation is critical — remove all loose rust, mill scale, oil, and contaminants before application per the manufacturer mixing and application guidelines. When using the activator, mix components thoroughly in the correct ratio before applying; do not add solvent beyond recommended limits. Ensure adequate ventilation and use appropriate respiratory protection as required by applicable safety data sheet guidelines.
