Quick Overview

939 High Thermal Conductive Addition-Type Potting Silicone is mixed by liquid organ silicone and ceramic thermal conductive powder, split charging to A and B two component. It is able to curing under room temperature or with heating temperature, the higher the curing temperature, the faster the curing speed. During reaction of this product, no by-product, it is widely used for potting of LED lighting, Power Supply Module and so on, which play a good role at thermal conductive, insulation, waterproof and flame retardant. Its flame retardant grade is up to UL94-V0, which is also completely compliant with EU ROHS directive.
