Silicone Encapsulants & Potting

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.
