MacDermid Alpha Electronics Solutions Thermally Conductive Epoxy Potting Compound ER2221

Product Description ER2221 thermally conductive epoxy potting compound has been formulated as high temperature resistant and thermally conductive encapsulation resin which retains excellent characteristics throughout thermal cycling. ER2221 exhibits excellent thermal resistance up to an operating temperature of 150°C and has an enhanced thermal conductivity value in comparison to other encapsulants of 1.20W/m.K. It is a filled resin system, however the viscosity of the mixed system is low in comparison to other resins with a similar filler loading. This allows the mixed resin to be easily mixed and can flow between components and devices with limited spacing. The fillers used in this resin are also non-abrasive meaning that there is less wear on dispensing machinery. ER2221 is an excellent choice for encapsulating an electronic device which requires high levels of thermal resistance and protection such as automotive, aerospace, industrial or other applications which are subject to harsh environments. For more information please refer to the TDS, our technical support team are also on hand to discuss your application requirements further. Key properties Two component black epoxy resin Excellent high temperature resistance up to 150°C Enhanced thermal conductivity Low viscosity for a filled system; Does not contain abrasive fillers; low wear on dispensing machinery UL94 V-0 Approval RoHS Compliant
