Lord Adhesives Thermoset™ 300/65 Epoxy System
Categories:	Polymer; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	LORD Thermoset 300/65 epoxy system is a two-component, general purpose filled epoxy system which offers superior thermal conductivity, improved shock resistance and lower coefficient of thermal expansion compared to unfilled epoxy systems. Handling and cured properties of the two-component epoxy system are dependent on the hardener used with Thermoset 300 epoxy resin. Features: maintains low viscosity for complete and void-free encapsulation. cures to a high gloss surface, free of “blush” or “sweat-out”. high surface hardness provides good impact and mar resistance. cured properties obtained even when cured in high humidity environments.
