Lord Adhesives Thermoset/CoolTherm™ EP 340/18 Epoxy System Epoxy Resin System
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: LORD CoolTherm™ EP-340/18 epoxy system is a two-component system designed to provide maximum thermal conductivity and outstanding mechanical properties. CoolTherm EP-340/18 system offers a very low coefficient of thermal expansion and is appropriate for applications where the expansion and contraction of an epoxy encapsulation system must be maintained. Handling and cured properties of the two-component epoxy system are dependent on the hardener used with CoolTherm EP-340 epoxy resin.

Features: provides excellent heat resistance for a room temperature cured system.
