CoolTherm® EP-340/70 epoxy system is a two-component system designed to provide maximum thermal conductivity and outstanding mechanical properties. CoolTherm EP-340/70 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.

Features and Benefits:
• Low Viscosity – provides low viscosity and surface tension, enabling void-free casting without a vacuum step.
• Convenient – provides a working life of over one hour; appropriate for cured system that experiences operating temperature of 130°C or below.
• UL Rated – cured system is UL 94 HB certified.

Shelf Life/Storage:
Shelf life of CoolTherm EP-340 resin is six months when stored at 25°C in original, unopened container. The material must be periodically rotated within its container to minimize settling.

Shelf life of Thermoset Hardener No. 70 is two years from date of manufacture when stored at 25°C in original, unopened container.
