Lord Adhesives CoolTherm™ SC-324 XLW Thermally Conductive Silicone Encapsulant
Categories: Polymer; Thermoset; Silicone; Silicone, RTV, Encapsulation Grade

Material Notes: LORD CoolTherm™ SC-324 XLW thermally conductive silicone encapsulant is a two-component system designed to provide excellent thermal conductivity for electrical/electronic encapsulating applications, while retaining desirable properties associated with silicones.

Features: exhibits low shrinkage and stress on components as it cures. composed of an addition-curing polydimethyl siloxane polymer that will not depolymerize when heated in confined spaces. maintains low viscosity for ease of component encapsulation compared to other highly thermal conductive materials. provides excellent thermal shock resistance and flame retardancy.
