It prepares the substrate by cleaning, activating, and optimising the surface chemistry before tape application, delivering a stronger and more reliable bond on materials including metal, glass, plastic, wood, concrete, and painted surfaces.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAdhesion promoter for use with 3M VHB and other high-strength bonding tapes\u003c\/li\u003e\n\u003cli\u003eSuitable for metal, glass, PE, PP, ABS, PET\/PBT blends, concrete, wood, and painted metal\u003c\/li\u003e\n\u003cli\u003eRemoves contaminants and activates surface energy for improved tape contact\u003c\/li\u003e\n\u003cli\u003eEnhances chemical interaction between tape and substrate\u003c\/li\u003e\n\u003cli\u003eEssential for low-energy or challenging surfaces where tape alone may not achieve full bond strength\u003c\/li\u003e\n\u003cli\u003eSupplied in a 236ml tin\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eWhen bonding with VHB tapes, surface preparation is critical. Even on apparently clean metal or painted surfaces, residual oils, moisture, or surface oxidation can significantly reduce bond strength over time. Applying 3M Primer 94 before the tape ensures the surface is properly activated and contaminant-free, maximising the long-term adhesion performance of the tape.\u003c\/p\u003e\u003cp\u003eBefore applying the primer, clean contaminated surfaces with a 50\/50 mixture of isopropyl alcohol and water using a clean, lint-free cloth. Allow the surface to dry completely before applying the primer and allow the primer to dry before applying the tape.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSolar panel rail and mounting tape installations on metal and sandwich panel roofs\u003c\/li\u003e\n\u003cli\u003eVHB tape bonding on painted metal, glass, and plastic substrates\u003c\/li\u003e\n\u003cli\u003eSignage, construction, and automotive assembly applications\u003c\/li\u003e\n\u003cli\u003eAny application where VHB tape is used on a low-energy or challenging surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eInstallation and Safety Notes\u003c\/h3\u003e\u003cp\u003eUse in a well-ventilated area. Keep away from heat sources and open flame. Allow primer to dry fully before applying tape. Follow the 3M product data sheet for full application guidance and safety information. For solar mounting applications, ensure the tape and primer are rated for the expected load, wind uplift, and temperature range of the installation.\u003c\/p\u003e","brand":"Voltacon","offers":[{"title":"Default Title","offer_id":47912255717710,"sku":"3M-PR94","price":36.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/3m-primer-94-mounting-vhb-tape-rails-260ml-780085.jpg?v=1747945109","url":"https:\/\/voltaconsolar.com\/products\/3m-primer-94-adhesion-promoter-236ml","provider":"VoltaconSolar","version":"1.0","type":"link"}
