Supplied as a 1-gallon kit containing equal volumes of Part B and Part A, it mixes at a 1:1 ratio and delivers a 70-minute work life, allowing ample time for careful dispensing into enclosures or around sensitive assemblies. Handling strength is reached in approximately 3 hours. The low viscosity formula flows easily into voids and tight geometries without requiring specialized mixing equipment. It is non-corrosive to copper and non-exotherming, making it well suited for heat-sensitive electronic assemblies where thermal runaway during cure is a concern.\u003c\/p\u003e\n\u003cp\u003eThis compound is used in potting and bonding applications across residential and commercial electrical, HVAC control board manufacturing, and general electronics assembly. Its high-flow characteristics make it effective for filling enclosures around transformers, sensors, PCBs, and terminal blocks. Electricians, electronics technicians, and OEM production operators are the primary installers. The black color provides a finished appearance and basic UV opacity when components are potted in open enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-part rigid epoxy with a 1:1 mix ratio for straightforward dispensing\u003c\/li\u003e\n  \u003cli\u003e70-minute work life provides extended open time for complex potting setups\u003c\/li\u003e\n  \u003cli\u003eHandling strength achieved in approximately 3 hours after mixing\u003c\/li\u003e\n  \u003cli\u003eLow viscosity and high flow for thorough void fill around electronic components\u003c\/li\u003e\n  \u003cli\u003eNon-corrosive to copper, safe for use directly against wiring and terminals\u003c\/li\u003e\n  \u003cli\u003eNon-exotherming cure reduces thermal stress on heat-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for potting and bonding electronic and electrical components where a rigid, low-viscosity two-part epoxy compound is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis compound is typically applied by electricians, electronics technicians, or OEM assembly personnel. De-energize all circuits and discharge any capacitors before potting live assemblies. Measure and mix Part A and Part B in the correct 1:1 ratio by volume to ensure full cure; incomplete mixing is the most common cause of adhesion failure. Work within the 70-minute pot life and allow adequate cure time before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMix Ratio\u003c\/strong\u003e: 1:1 (Part A to Part B)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWork Life\u003c\/strong\u003e: 70 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandling Strength\u003c\/strong\u003e: Approximately 3 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Size\u003c\/strong\u003e: 1 gallon (Part A) plus 1 gallon (Part B)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20.64 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200822636\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: 7000121253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347638878514,"sku":"7000121253","price":2828.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518124.jpg?v=1782110157","url":"https:\/\/voomisupply.com\/products\/3m-7000121253-epoxy-potting-compound-270-black-1-gal-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
