Lord Adhesives CoolTherm™ EP-2000 Thermally Conductive Epoxy Encapsulant
Categories: Polymer; Thermoset; Epoxy; Epoxy, Thermally Conductive

Material Notes: LORD CoolTherm™ EP-2000 encapsulant is a two-component, low viscosity epoxy system designed for encapsulation of motor stators, transformer coils, and other devices with small-diameter, tightly-packed windings. CoolTherm EP-2000 encapsulant provides high-temperature stability combined with excellent electrical insulation.

Features: provides lower motor end winding temperatures during high-power operation. provides fine-particle filler and low viscosity; self-levels to fill voids in motor stators/rotors, transformer coils and other electrical devices. cured material resists cracking during multiple thermal cycles from sub-zero temperatures to 200°C.
