Rust-oleum 9809377 Dtm Urethane Mastic Coating 5 Gallon

Product Description

The RUST-OLEUM 9809377 is a two-component, direct-to-metal (DTM) urethane mastic coating formulated for industrial corrosion protection. This high-solids, high-build finish bonds directly to prepared metal without a separate primer coat, reducing labor steps on the job. It delivers gloss retention and color durability in moderate to severe industrial environments where moisture, chemical exposure, and mechanical wear are ongoing concerns. The 5-gallon unit is suited for large-scale application on tanks, structural steel, towers, and heavy equipment. A two-year rust-proof guarantee backs the coating's corrosion resistance performance.

This coating is engineered for industrial and commercial settings where aggressive environmental conditions demand a durable topcoat. Typical applications include storage tanks, process equipment, metal towers, and fabricated structural components exposed to corrosive atmospheres. It meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities, making it appropriate for food and beverage processing plant infrastructure. Licensed industrial painters and maintenance contractors handle most applications at this scale.

Key Features

• Direct-to-metal formula — self-priming, covers in a single coat
• Two-component system — base and activator ordered separately for controlled mixing
• High-solids, high-build, sag-resistant formulation for vertical and overhead surfaces
• Two-year rust-proof guarantee with maximum corrosion resistance
• Meets USDA incidental food contact requirements; accepted in federally registered Canadian food facilities
• Suitable for moderate to severe industrial environments including tanks, towers, and metal equipment

Compatibility

For best results, apply over HS9300 System Epoxy Primer in red or gray. Designed for use on prepared metal substrates in moderate to severe industrial service environments.

Installation Notes

Application is typically performed by industrial painting contractors or trained maintenance technicians familiar with two-component coatings. Follow the manufacturer's mixing ratio instructions precisely when combining the base and activator components — improper ratios affect cure hardness and adhesion. Surface preparation to the appropriate SSPC standard is required before application. Review applicable local VOC regulations and facility safety requirements before use in enclosed or food-adjacent spaces.
