CoolTherm® SC-1500 Thermally Conductive Silicone Gap Filler Where to Buy

Product Information

LORD CoolTherm® SC-1500 thermally conductive silicone gap filler is a two-component system designed to provide excellent thermal conductivity for electronic applications, while retaining desirable properties associated with silicones.

Shelf Life

Shelf life of each component is five months when stored at 25°C in original, unopened container.

CoolTherm SC-1500 gap filler evolves minute quantities of hydrogen gas. Do not repackage or store material in unvented containers. Adequately ventilate work area to prevent the accumulation of gas.

Features and Benefits

Low Stress – exhibits low shrinkage and stress on components as it cures.

Durable – composed of an addition-curing polydimethyl siloxane polymer that will not depolymerize when heated in confined spaces.

Environmentally Resistant – provides excellent thermal shock resistance.

UL Rated – provides excellent flame retardancy; UL 94 V-0 certified.
