Rust-oleum 9808375 Dtm Urethane Mastic Coating 5 Gallon

Product Description

The RUST-OLEUM 9808375 is a two-component, direct-to-metal (DTM) urethane mastic coating formulated for high-performance corrosion protection in moderate to severe industrial environments. Supplied in a 5-gallon container with a gloss finish, this high-solids, high-build formula applies directly to metal surfaces without a separate primer coat, though priming is recommended for best results. It resists sag during application and delivers long-term color retention under aggressive conditions. The base and activator are ordered separately. This product meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities.

The 9808375 is designed for industrial and commercial maintenance painting on tanks, towers, structural steel, and metal equipment exposed to corrosive or chemically aggressive atmospheres. It is a fit for facilities that require a durable single-coat topcoat with built-in rust inhibition. The two-year rust-proof guarantee makes it a practical specification for extended maintenance cycles in processing plants, water treatment facilities, and heavy industrial settings.

Key Features

• Direct-to-metal formula eliminates mandatory primer step, reducing labor time
• High-solids, high-build, sag-resistant formulation for vertical and overhead surfaces
• Two-component urethane system delivers extreme durability and chemical resistance
• Two-year rust-proof guarantee for maximum corrosion protection
• Meets USDA requirements for incidental food contact
• Accepted for use in federally registered Canadian food facilities

Compatibility

Formulated for direct application to metal substrates including tanks, towers, and industrial equipment in moderate to severe service environments. For optimal adhesion and corrosion resistance, prime first with the HS9300 System Epoxy Primer in red or gray before applying this topcoat.

Installation Notes

Application should be performed by qualified industrial painting contractors or maintenance professionals familiar with two-component coating systems. Mix base and activator according to manufacturer instructions before application; pot life limitations apply once components are combined. Ensure adequate ventilation, appropriate PPE, and compliance with local VOC regulations during application and curing. Do not apply to surfaces below minimum temperature thresholds or when moisture is present on the substrate.
