This low-viscosity compound offers a 1:1 mix ratio with a 70-minute work life, reaching handling strength in approximately 3 hours. It is non-corrosive to copper, non-exothermic, and exhibits high flow characteristics, making it well suited for production and field applications where thermal runaway and copper corrosion are concerns. This listing is for Part A only; Part B must be sourced separately to complete the B\/A system.\u003c\/p\u003e\n\u003cp\u003eThis compound is used in residential, commercial, and industrial electrical and electronic assembly environments. Typical applications include potting transformers, sensors, circuit board assemblies, and other electrical components requiring encapsulation for mechanical protection or environmental sealing. The low viscosity allows the material to flow into tight geometries and around component leads before cure, reducing voids. Electronics assemblers, industrial maintenance technicians, and electrical contractors working with encapsulated components are the primary installers of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1:1 mix ratio simplifies metering and dispensing with standard two-component equipment\u003c\/li\u003e\n  \u003cli\u003e70-minute work life provides adequate open time for production and repair applications\u003c\/li\u003e\n  \u003cli\u003eHandling strength achieved in approximately 3 hours at room temperature\u003c\/li\u003e\n  \u003cli\u003eLow viscosity promotes high flow and void-free fill in tight component geometries\u003c\/li\u003e\n  \u003cli\u003eNon-corrosive to copper, protecting sensitive electrical contacts and conductors\u003c\/li\u003e\n  \u003cli\u003eNon-exothermic cure reduces risk of thermal damage to heat-sensitive components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as Part A in the 3M Scotch-Weld Epoxy Potting Compound 270 B\/A two-part system.

De-energize and lock out all electrical assemblies before potting. Use calibrated two-component dispensing equipment to maintain the 1:1 ratio; off-ratio mixing will result in incomplete cure. Work in a well-ventilated area and observe applicable safety data sheet requirements for skin and eye protection.\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 (B\/A by volume)\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\u003eViscosity\u003c\/strong\u003e: Low\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCure Type\u003c\/strong\u003e: Non-exothermic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCopper Compatibility\u003c\/strong\u003e: Non-corrosive to copper\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\u003eContainer Size\u003c\/strong\u003e: 5 gallon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.29 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200822650\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: 7000046463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346522964274,"sku":"7000046463","price":3670.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518112.jpg?v=1782082688","url":"https:\/\/voomisupply.com\/products\/3m-7000046463-epoxy-potting-compound-270-black-part-a-5-gal","provider":"Voomi Supply","version":"1.0","type":"link"}
