Thumbnail Filmstrip of Black Thermally Conductive Epoxy Encapsulating & Potting Compound, 2 litres (0.5 gallons) liquid Images
MG Chemicals Thermally Conductive Epoxy is 100% solids. It provides all of the protection our standard potting compounds do, but allows trapped heat to escape more readily. As well, this system has an extended working time and a convenient one to one mix ratio making it ideal for large batches, high volume production, and automatic dispensing.
This is designed to be a high quality solution. It is formulated with undiluted Bis F resin, so it has superior physical properties to conventional diluted Bis A systems. Cured with a polyamide, it is not as brittle as the more common amine cured thermally conductive systems, and can be machined to shape. Filled with high purity aluminum oxide powder it has excellent thermal conductivity at reasonable cost, and is free of zinc oxide and other environmental pollutants. As well, it is pigmented black for maximum radiative cooling via black body radiation.
