| Product Description: Master Bond Polymer System EP21TDC-2AN is a two component flexible epoxy resin compound for high performance bonding, sealing, coating, and encapsulation. This system’s thermal conductivity is formulated to fully cure at ambient temperature or more quickly at elevated temperatures with an easy to handle one to three mixing ratio by weight. The cured compound exhibits a high elongation (greater than 25%); good for a thermally conductive epoxy. After mixing EP21TDC-2AN generates a very low exotherm, which allows for a long working life. This epoxy compound exhibits good tensile shear and peel strength for bonding and sealing. It adheres well to a wide variety of substrates including metals, glass, ceramics, rubbers and many plastics. This cured adhesive is an excellent electrical insulator with superior chemical resistance to water, fuels and many solvents. It excels at withstanding thermal shock, thermal cycling and mechanical shock. This compound features a service temperature range of 4K to 250°F and has be en successfully employed in a number of cryogenic applications. Master Bond EP21TDC-2AN is a versatile system that offers the structural benefits of an epoxy, yet incorporates flexibility and thermal conductivity. It is widely used in the electronic, electro-optical and related industries. The color of Part A is light gray; Part B is gray. Product Advantages: - Convenient mixing: non-critical one to three mix ratio by weight
