It mixes at a 2:1 ratio with its corresponding Part B and delivers a 20-minute work life with handling strength achieved in approximately 2 hours. The 420LH formulation is engineered for good shear and peel strength alongside solid impact resistance and long-term durability. Licensed adhesive applicators and industrial maintenance technicians are the primary installers. This listing covers the 5-gallon Part A container only; Part B must be sourced separately.\u003c\/p\u003e\n\u003cp\u003eThe 420LH system is suited for structural bonding applications in environments where halogen content must be kept low, such as certain electronics, aerospace, and fire-safety-sensitive assemblies. The adhesive bonds effectively to a broad range of substrates including metals, composites, and many rigid plastics. Its extended work life makes it practical for larger bond areas or assemblies that require positioning time before cure begins.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-halogen formulation suitable for applications with restricted halogen content requirements\u003c\/li\u003e\n  \u003cli\u003e2:1 mix ratio (Part A to Part B) for straightforward metering and dispensing\u003c\/li\u003e\n  \u003cli\u003e20-minute work life allows time for positioning and assembly adjustments\u003c\/li\u003e\n  \u003cli\u003eHandling strength reached in approximately 2 hours after mixing\u003c\/li\u003e\n  \u003cli\u003eGood shear, peel, and impact strength for structural bonding demands\u003c\/li\u003e\n  \u003cli\u003eBonds to a wide range of surfaces including metals, composites, and rigid plastics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as the Part A (Accelerator) component in the 3M Scotch-Weld Epoxy Adhesive 420LH two-part B\/A system.

Ensure both components are at the recommended application temperature before mixing and verify the correct 2:1 mix ratio is maintained throughout the job. Work in a well-ventilated area and follow applicable safety data sheet guidance for personal protective equipment. Do not mix partial quantities that cannot be confirmed at the correct ratio, as off-ratio batches will not cure to rated strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMix Ratio\u003c\/strong\u003e: 2:1 (Part A to Part B)\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: 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\u003eComponent\u003c\/strong\u003e: Part A (Accelerator)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.97 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHalogen Content\u003c\/strong\u003e: Low halogen\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: 7010365971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344404218162,"sku":"7010365971","price":10392.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523907.jpg?v=1782035100","url":"https:\/\/voomisupply.com\/products\/3m-7010365971-scotch-weld-epoxy-adhesive-420lh-part-a","provider":"Voomi Supply","version":"1.0","type":"link"}
