epoxySet introduces the EC-1019, specialized epoxy potting compound. This system utilizes unique chemistry and fillers to offer a thermally conductive compound that has very small particulate size of about 15um. The small particles allow it to penetrate and fill intricate voids. The thermal conductivity of 2.0 W/m°K makes for excellent heat dissipation in temperatures ranges of -40 to 220°C. The unique chemistry drastically reduces cracking compared with traditional, rigid materials. Its low CTE of 22 ppm/°C keeps stresses to a minimum.
It is used for tightly packed windings in motor stators/rotors, transformer coils and power supplies as well as other elaborate potting applications where thermal strain is a concern.
EC-1019 has excellent resistance to moisture and chemicals and is a superior electrical insulator. It is available in quart, gallon and pail kits with supply in about 2 weeks.
