Curing epoxy features low thermal resistance

EP30TC exhibits a thermal conductivity of 18-20 BTU•in/ft2•hr•°F [2.60-2.88 W/(m•K)] and has the ability to be applied in sections as thin as 5-15 microns, resulting in a low thermal resistance of 7-10 x 10-6 K•m2/W.

This compound is a reliable electrical insulator and has a volume resistivity of over 1014 ohm-cm. It is serviceable over the wide temperature range of -100°F to +300°F [-73°C to +149°C]. EP30TC features a low viscosity with excellent flow properties making it well suited for coating and potting applications. As a two part system, it requires a 10 to 1 mix ratio by weight.

Color coding facilitates mixing with Part A being gray and Part B being clear. It can be cured at room or elevated temperatures, but to achieve optimum properties, the recommended cure schedule is overnight at ambient temperature followed by 2-3 hours at 150-200°F.

This system bonds well to metals, composites, ceramics, glass and many plastics. It delivers superior physical strength properties, with a tensile strength of 5,000-6,000 psi, a compressive strength of 24,000-26,000 psi and a tensile modulus of 500,000-550,000 psi.

Dimensionally stable, EP30TC also has very low shrinkage upon curing and a low coefficient of thermal expansion. This product is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits, as well as in premixed and frozen syringes.
