CoolTherm® SC-6709/6731 Silicone Encapsulant Where to Buy
Product Information
LORD CoolTherm® SC-6709/6731 silicone encapsulant is a two-component, solvent-free RTV silicone system. CoolTherm SC-6709/6731 encapsulant system is an ideal potting compound for any application where rapid heat transfer, high temperature service and a flexible system are required.
Shelf Life
Shelf life of each component is six months from date of manufacture when stored at 25°C in original, unopened container.
Features and Benefits
Low Viscosity – maintains low viscosity for complete and void-free encapsulation.
High Thermal Conductivity – provides thermal conductivity for applications where superior heat dissipation are required.
Low Coefficient of Thermal Expansion – minimizes the possibility of cracking during severe temperature cycling.
Broad Temperature Range – can be used on parts and devices that experience operating temperatures from -68°C to +205°C.
