ER2220 Thermally Conductive Epoxy

In Stock

ER2220 is a flame retardant, thermally conductive, two part encapsulation compound based on epoxy technology. Designed to meet increasing demands for efficient thermal dissipation, ER2220 combines ease of processing with an enhanced thermal conductivity when compared to traditional thermally conductive encapsulants. Combined with flame retardance achieving UL94 V-0 level, ER2220 provides the ultimate in protection and performance for avast array of applications, including those in the rapidly expanding LED industry.
