Sold as AC79, this colorless primer is designed to prepare elastomeric substrates that typically resist standard adhesive bonding. It ships in a 2 fl oz unit and weighs 0.15 pounds. Adhesive technicians, maintenance professionals, and industrial assembly workers apply this primer directly to each elastomeric surface before applying the instant adhesive, creating a more reliable bond on substrates that would otherwise bond poorly or fail prematurely.\u003c\/p\u003e\u003cp\u003eAC79 is used in applications where silicone, EPDM, and other elastomeric materials must be bonded using instant adhesives. Typical use cases include sealing, gasketing, and repair work on rubber components in HVAC systems, plumbing assemblies, and general industrial maintenance. The primer is applied to each mating surface and allowed to flash off before the instant adhesive is applied. It is particularly useful in field service environments where elastomeric parts need fast, reliable bonding without specialized surface preparation equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCalifornia-compliant formulation for use in regulated environments\u003c\/li\u003e\n\u003cli\u003eColorless finish leaves no visible residue on bonded surfaces\u003c\/li\u003e\n\u003cli\u003ePrepares silicone, EPDM, and other elastomers for instant adhesive bonding\u003c\/li\u003e\n\u003cli\u003eApply to each substrate surface before adhesive application\u003c\/li\u003e\n\u003cli\u003eCompact 2 fl oz size suited for field service and bench work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with instant adhesives on elastomeric substrates including silicone and EPDM rubbers.

Work in a well-ventilated area, as instant adhesive primers and cyanoacrylates produce vapors that can cause irritation. Keep the applicator cap sealed when not in use to prevent evaporation and contamination. Follow all applicable safety data sheet guidelines for storage and handling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number\u003c\/strong\u003e: AC79\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Colorless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume\u003c\/strong\u003e: 2 fl oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051115313882\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100039262\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343048606002,"sku":"7100039262","price":248.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528441.jpg?v=1782014840","url":"https:\/\/voomisupply.com\/products\/3m-7100039262-instant-adhesive-primer-ac79-2-fl-oz","provider":"Voomi Supply","version":"1.0","type":"link"}
