CSL503 is a one-part, moisture curing RTV (Room Temperature Vulcanizing) silicone sealant that cures to a tough rubber gasket.
CSL503 is ideal for extreme heat applications where high levels of protection, adhesion, elasticity and longevity are desired.
CSL503 is designed to maintain maximum performance in a continuous temperature environment of 300°C (572°F).
CSL503 gasket will remain permanently flexible even after 7 day continuous exposure to maximum temperatures.
CSL503 resists aging, weathering and thermal cycling without hardening, shrinking or cracking.
CSL503 also provides excellent resistance to vibration and shock and severe weathering conditions.
- Extreme temperature performance
- Superior flexibility
- Replaces most cut gaskets
- Easy application
- Versatile sealant/adhesive
- Unaffected by extreme temperatures
- Resists moisture, vibration, mechanical and thermal shock
- Easily applied to complex geometries
CSL503 is an industrial gasket maker and sealant designed to provide reliable form-in-place gaskets for mechanical assemblies. CSL503 replaces almost any cut gasket and can be used to coat pre-cut gaskets to increase reliability. Typical applications include: automotive assembly, appliance gaskets, ductwork, fireplace seals, high temperature spacers, oven doors and flues on high temperature applications.
A high temperature sealant is also available in black and in a self-leveling formulation.
