High temperature resistance flowable potting silicone compound
Flowable, 1-part potting Silicone sealant and encapsulant, cures at room temperature to form a tough rubber seal with high temperature resistance.
It is a flowable, smooth, 1-part RTV (room temperature vulcanizing) oxime silicone paste sealant that cures at room temperature on exposure to moisture in the air to form a tough, flexible, waterproof, oil-resistant silicone rubber bond. It resists temperatures up to 320°C for 1 hour, making it well suited for sealing applications with high temperature. It resists aging, weathering and thermal cycling without hardening, shrinking or cracking.
