Sold as a colorless liquid in a 1-gallon container, AC79 primer is applied to elastomeric substrates before bonding with instant adhesives to improve adhesion where standard surface prep falls short. Adhesive technicians, industrial maintenance crews, and trade professionals use this primer when working with surfaces that resist direct bonding. It weighs 8.19 pounds per unit and is sold individually.\u003c\/p\u003e\n\u003cp\u003eAC79 primer is intended for use on elastomeric substrates including silicone and EPDM rubber, as well as other elastomers that are inherently difficult to bond. Typical applications include gasket assembly, rubber component repair, and industrial maintenance scenarios where instant adhesive performance on low-surface-energy materials is required. The California-compliant formulation meets VOC regulations applicable in strict-compliance states, making it suitable for use in regulated work environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCalifornia-compliant VOC formulation for use in regulated environments\u003c\/li\u003e\n  \u003cli\u003ePromotes adhesion on silicone, EPDM, and other difficult elastomeric surfaces\u003c\/li\u003e\n  \u003cli\u003eColorless formula leaves no visible residue on treated substrates\u003c\/li\u003e\n  \u003cli\u003eApply to each elastomeric surface prior to instant adhesive bonding\u003c\/li\u003e\n  \u003cli\u003e1-gallon container suitable for high-volume or shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a pre-treatment primer with instant adhesives on elastomeric substrates including silicone and EPDM rubber.
