CoolTherm® EP-340/18 Epoxy System Where to Buy
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.
Shelf life of CoolTherm EP-340 resin is six months from date of manufacture 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. 18 is two years from date of manufacture when stored in a wellventilated area at 25°C in original, unopened container.
