CoolTherm® SC-6703 Thermally Conductive Silicone Encapsulant Where to Buy
Product Information
LORD CoolTherm® SC-6703 thermally conductive silicone encapsulant is a two-component system designed to provide thermal conductivity for encapsulating densely packed power units.
Shelf Life
Shelf life of each component 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 maintain maximum shelf life. Settling will occur if not mixed.
Features and Benefits
Low Stress – exhibits low shrinkage and stress on components as it cures.
Environmentally Resistant – provides excellent thermal shock resistance.
UL Rated – meets requirements of UL 94 V-O standard; provides excellent flame retardancy.
