ER2224 Thermally Conductive Resin

In Stock

ER2224 Epoxy potting compound is a highly thermally conductive resin (1.0 W/m*K) which also offers strong thermal cycling properties. It is an off-white resin allowing it to blend with LED designs, dissipating heat from the LED and extending the units operating lifetime and reliability while offering excellent environmental protection against the elements as well as showing good chemical resistance.

It has good high temperature stability with a wide operating temperature range which makes it suitable for a wide variety of applications.
