Product Description: Master Bond Polymer System EP21TDC 2AO is a two component highly flexible epoxy resin compound for high performance bonding sealing, coating and encapsulation. It is formulated to cure fully at ambient temperatures or more quickly at elevated temperatures with an easy to use one to three mixing ratio by weight. The cured compound exhibits a high elongation (greater than 25%), truly exceptional for a thermally conductive epoxy. After mixing EP21TDC-2AO generates a very low exotherm, which allows for a long working life. This epoxy resin compound exhibits good tensile shear and peel strength for bonding and sealing many different substrates including metals, glass, ceramics, vulcanized rubber and many plastics. The cured epoxy is an excellent electrical insulator with superior chemical resistance to water, fuels and many solvents. Most noteworthy is its ability to withstand thermal shock, thermal cycling and mechanical shock. Featuring a service temperature range of 4K to 250°F, it has been successfully employed in a number of cryogenic applications. Master Bond EP21TDC-2AO is an exceptionally versatile system that offers the structural benefits of an epoxy, yet incorporates flexibility and impressive thermal conductivity. It is widely used in the electronic, electro-optical and related industries. The color of Part A is gray; Part B is offwhite.Product Advantages: - Convenient mixing: non-critical one to three weight ratio
