Sold in a 5-gallon container, this off-white Part B pairs with its corresponding Part A hardener at a 2:1 mix ratio to form a structural adhesive with a 20-minute working life and handling strength reached in approximately 2 hours. The cured adhesive delivers good shear and peel strengths along with resistance to impact and general wear. Licensed applicators and assembly professionals install this product in bonding operations across industrial, manufacturing, and construction environments.\u003c\/p\u003e\u003cp\u003eThis adhesive is suited for bonding metals, ceramics, wood, and select plastics in demanding assembly or repair applications. The 2-hour handling time supports production workflows where moderate cure speed is required. The 5-gallon container size is intended for high-volume use, making it appropriate for shop-floor or production-line dispensing operations rather than small-batch field repairs. It is the Part B component only and must be used in conjunction with the corresponding Part A to achieve the intended adhesive performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-part toughened epoxy formulation with a 2:1 mix ratio (B to A)\u003c\/li\u003e\n\u003cli\u003e20-minute working life allows time for part positioning and adjustment\u003c\/li\u003e\n\u003cli\u003eHandling strength reached in approximately 2 hours\u003c\/li\u003e\n\u003cli\u003eBonds to metals, ceramics, wood, and select plastics\u003c\/li\u003e\n\u003cli\u003eGood shear and peel strengths with impact resistance\u003c\/li\u003e\n\u003cli\u003e5-gallon container sized for high-volume production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThis is the Base (Part B) component of the Scotch-Weld Epoxy Adhesive 420 two-part system.

Mix Part B and Part A at the specified 2:1 ratio only; incorrect ratios will compromise cure and final strength. Follow all applicable safety data sheet guidelines for ventilation, personal protective equipment, and storage. Consult the product technical data sheet for substrate-specific preparation and curing requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix Ratio\u003c\/strong\u003e: 2:1 (B to A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWork Life\u003c\/strong\u003e: 20 minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling Strength Time\u003c\/strong\u003e: Approximately 2 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Off-white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 5 gallon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 7100001145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343133671730,"sku":"7100001145","price":1879.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518103.jpg?v=1782017670","url":"https:\/\/voomisupply.com\/products\/3m-7100001145-epoxy-adhesive-part-b-5-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
