Formulated as a non-sag adhesive, it is designed for use with the corresponding Part B component in a 2:1 mix ratio. Work life is approximately 20 minutes, with handling strength achieved in roughly 2 hours. The cured bond delivers good shear and peel strength along with solid impact resistance and durability. This product is typically applied by industrial maintenance technicians, assembly professionals, and skilled tradespeople working with demanding bonding applications across metals, ceramics, wood, and select plastics.\u003c\/p\u003e\n\u003cp\u003eThe 420NS system is suited for structural and semi-structural bonding in environments where non-sag performance is required on vertical or overhead surfaces. Its toughened formulation handles dynamic loads and vibration better than standard rigid epoxies. Typical applications include metal-to-metal bonding, ceramic repair, wood assembly, and plastic substrate bonding in industrial, commercial, and maintenance-of-equipment contexts. This listing covers Part A only and must be paired with the corresponding Part B component to complete the two-part system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eToughened, non-sag two-part epoxy formulation resists slumping on vertical surfaces\u003c\/li\u003e\n  \u003cli\u003e2:1 mix ratio for use with the designated Part B component\u003c\/li\u003e\n  \u003cli\u003eApproximately 20-minute work life allows positioning and adjustment before cure begins\u003c\/li\u003e\n  \u003cli\u003eHandling strength reached in approximately 2 hours after mixing\u003c\/li\u003e\n  \u003cli\u003eBonds to metals, ceramics, wood, and select plastics\u003c\/li\u003e\n  \u003cli\u003eGood shear strength, peel strength, and impact resistance after cure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as Part A of the Scotch-Weld Epoxy Adhesive 420NS two-part system.

Before dispensing, ensure both Part A and Part B are at the recommended application temperature and that all surfaces are clean, dry, and free of oils or contaminants. Follow the manufacturer safety data sheet for ventilation requirements and personal protective equipment. Do not substitute Part B components from other product lines, as mix ratios and cure chemistry are system-specific.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMix Ratio (B:A)\u003c\/strong\u003e: 2:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWork Life\u003c\/strong\u003e: approximately 20 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandling Strength\u003c\/strong\u003e: approximately 2 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent\u003c\/strong\u003e: Part A (Accelerator)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.66 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011581330\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7100084536\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346385469746,"sku":"7100084536","price":66447.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523263.jpg?v=1782078898","url":"https:\/\/voomisupply.com\/products\/3m-7100084536-scotch-weld-epoxy-adhesive-420ns-black-part-a","provider":"Voomi Supply","version":"1.0","type":"link"}
