CoolTherm® SC-6708 WHT/6732 Silicone System Where to Buy
Product Information
CoolTherm® SC-6708 WHT/6732 silicone system is a two-component, thermally conductive encapsulant system with good electrical properties. The encapsulant system is an ideal potting compound for applications where a stress-free, heat conductive flexible system is required.
Shelf Life
Shelf life of CoolTherm SC-6708 WHT resin is six months from date of manufacture when stored at 25°C in original, unopened container.
Shelf life of Circalok 6732 hardener is one year from date of manufacture when stored at 25°C in original, unopened container.
Features and Benefits
Low Stress – exhibits low shrinkage and stress on components as it cures.
High Thermal Conductivity – provides thermal conductivity for applications where superior heat dissipation is required.
Durable – provides long lasting environmental protection; cures to a flexible elastomer with high temperature stability.
Broad Temperature Range – can be used on parts and devices that experience operating temperatures from -55°C to +205°C.
