Rust-oleum 9179402 Dtm Epoxy Mastic 1 Gallon Black

Product Description

The RUST-OLEUM 9179402 is a two-component, direct-to-metal (DTM) epoxy mastic coating formulated for high-performance protective applications. This 1-gallon black gloss unit is the base component of the 9100 System and requires a separately ordered activator to cure. The coating delivers a tough, durable finish with superior long-term resistance to solvents, chemicals, abrasion, and impact. It uses a 1:1 mixing ratio by volume, so no separate measuring is required. The formula is self-priming and adheres directly to a variety of substrates without a dedicated primer coat. Licensed applicators and industrial maintenance professionals are the primary installers.

The 9179402 is suited for industrial and commercial maintenance painting on steel, concrete, and other prepared substrates. Typical applications include structural steel, tank exteriors, floors, and equipment in facilities requiring chemical and corrosion resistance. The coating meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities. It is available in gallon and five-gallon containers. Four activator options are offered for specific conditions: Standard Activator (50-100 degrees F air and surface temps), Immersion Activator (fresh or salt water immersion up to 125 degrees F, not for potable water tanks), Low-Temperature Activator (40-60 degrees F air and surface temps), and Fast-Cure Activator (recoat in 4 hours at 70 degrees F and 50% RH).

Key Features

• Direct-to-metal self-priming formula bonds to steel, concrete, and a variety of substrates without a separate primer
• 1:1 mixing ratio with no measuring required — base and activator ordered separately
• Superior resistance to solvents, chemicals, abrasion, and impact for long-term protection
• Four activator options: Standard, Immersion, Low-Temperature, and Fast-Cure for application-specific needs
• Meets USDA incidental food contact requirements; accepted for federally registered Canadian food facilities
• Two-year rust-proof guarantee for maximum corrosion protection
• Less than 340 VOCs

Compatibility

Designed for direct application to metal and concrete substrates as part of the RUST-OLEUM 9100 System DTM Epoxy Mastic line. Activators are sold separately and must be matched to the specific application condition (temperature range, immersion service, or cure speed requirement).

Installation Notes

This product is a two-component coating and must be mixed with the appropriate RUST-OLEUM 9100 System activator before application — applying the base alone will not cure properly. Surface preparation to the manufacturer-specified cleanliness and profile standard is required before coating. Ensure adequate ventilation and follow all applicable local and federal safety regulations for solvent-borne coatings during mixing and application. Do not use the Immersion Activator version in potable water tanks.
