This low-viscosity compound offers a 1:1 mix ratio with a 70-minute work life, allowing adequate time for dispensing and positioning before cure. Handling strength is achieved in approximately 3 hours. The formula is non-corrosive to copper and non-exotherming, making it well suited for heat-sensitive assemblies. This 5-gallon container supplies the B side of the B\/A system and must be paired with the corresponding Part A to achieve a complete, cured compound.\u003c\/p\u003e\n\u003cp\u003eEpoxy Potting Compound 270 Part B is used in residential and commercial electrical and electronics assembly applications where reliable encapsulation of components is required. Typical installations include potting circuit boards, sensors, coils, and similar components where protection from moisture, vibration, and mechanical stress is needed. Its high-flow characteristic allows the compound to fill irregular cavities and voids around components without manual manipulation. Electronics assemblers, electrical contractors, and OEM production technicians are the primary users of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1:1 mix ratio simplifies dispensing with standard two-component equipment\u003c\/li\u003e\n  \u003cli\u003e70-minute work life provides extended open time for complex potting operations\u003c\/li\u003e\n  \u003cli\u003eHandling strength reached in approximately 3 hours after mixing\u003c\/li\u003e\n  \u003cli\u003eLow viscosity and high flow fill cavities around electronic components without voids\u003c\/li\u003e\n  \u003cli\u003eNon-corrosive to copper — safe for use directly around copper conductors and coils\u003c\/li\u003e\n  \u003cli\u003eNon-exotherming formulation reduces thermal risk to heat-sensitive components during cure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis product is the Base (Part B) component designed for use in the 3M Scotch-Weld Epoxy Potting Compound 270 B\/A two-part system.
