Silicone Products: Conformal Coating, Elastomers, Encapsulating & Potting, Moldmaking, Gels

ENCAPSULATING AND POTTING MATERIALS

Encapsulants and silicone potting materials are the ideal choice for protecting sensitive electronic components from extreme environments. Silicone encapsulants and silicone potting materials withstand temperatures from -115 to 300°C while protecting the components from vibration, moisture and atmospheric contaminants. QSi's product line consists of both tin and platinum curing systems in a variety of durometers and cure speeds, We also have thermally conductive encapsulants and potting materials and flame resistant adhesives that meet UL 94 V-0 requirements.
