Product Description

CSL 503 is a one part, moisture curing, room-temperature vulcanizing (RTV), 100% silicone sealant that cures to a tough rubber gasket and is ideal for high temperature applications.

CSL 503 is designed to maintain maximum performance in a continuous temperature environment of up to 315°C (600°F) and intermittent exposure up to 343°C (650°F). The gasket will remain permanently flexible even after 7 day continuous exposure to maximum temperatures.

CSL 503 resists aging, weathering and thermal cycling without hardening, shrinking, or cracking.
