Thermally Conductive Epoxy Resists High Temperatures

By Garrett Harmon | May 13, 2014

Formulated for bonding and sealing applications, Master Bond EP46HT-1AO is widely used in the aerospace, electronic and specialty OEM industries. Unlike most conventional two component epoxies, EP46HT-1AO cures with the addition of heat, which allows it to have a working life exceeding 24 hours. It has a forgiving 100 to 30 mix ratio by weight and bonds well to metals, composites, glass, ceramics and many plastics.

EP46HT-1AO combines thermal conductivity and electrical insulation properties. This dimensionally stable system provides a tensile strength over 7,500 psi, a compressive strength of 26,000 psi and a tensile lap shear strength greater than 1,500 psi at room temperature. EP46HT-1AO also withstands a variety of chemicals including oils, water, acids, bases and solvents.

This unique compound is serviceable over the temperature range of -73°C to +288°C (-100°F to +550°F) and offers a glass transition temperature of 215°C. It should be noted that EP46HT-1AO is relatively exothermic and should not be cured in sections greater than 20-30 thousandths of an inch thick and a bondline thickness is typically 2-7 thousandths of an inch.

This epoxy is available in ½ pint, pint, quart, gallon and 5 gallon container kits. Part A of this system is tan in color and Part B is moderately dark brown. EP46HT-1AO has a 6 month shelf life at ambient temperatures in original, unopened containers.
