The RUST-OLEUM 331254 is the Standard Activator for the 9100 System DTM Epoxy Mastic, a two-component, direct-to-metal industrial coating designed for heavy-duty corrosion protection. This activator pairs with a 9100 System base color at a 1:1 mixing ratio, eliminating the need for measuring equipment on the job. The formulated blend delivers superior resistance to solvents, chemicals, abrasion, and impact once cured. This Standard Activator is rated for air and surface temperatures of 50 to 100 degrees F, making it the general-purpose choice across most commercial and industrial coating applications. The unit ships as a 1-gallon container weighing 13.07 pounds.
The 9100 System DTM Epoxy Mastic is used in commercial and industrial settings where long-term corrosion protection is required on metal, concrete, and other hard substrates. The self-priming, direct-to-metal formula reduces prep steps and coat counts compared to conventional epoxies. The system meets USDA requirements for incidental food contact and is accepted for use in federally registered Canadian food facilities. Typical applications include structural steel, equipment housings, process piping, and facility floors in manufacturing, food processing, and maintenance environments. Licensed painters and industrial coating contractors are the primary installers.
Designed for use with RUST-OLEUM 9100 System DTM Epoxy Mastic base color components, which are ordered separately. This Standard Activator is formulated for applications where air and surface temperatures fall between 50 and 100 degrees F. Other activator options in the 9100 System include Immersion, Low-Temperature, and Fast-Cure variants for specialized conditions.
This product is part of a two-component system and must be combined with the corresponding 9100 System base color before application. Mix only what can be applied within the pot life of the combined system, as mixed material cannot be stored. Surface preparation should follow standard industrial coating practices, including cleaning and degreasing the substrate. Follow all local VOC regulations and applicable safety codes when applying solvent-borne epoxy coatings in enclosed or semi-enclosed spaces.
