Gasketing Sealants


CSL537 Low Viscosity Self-leveling Form-in-Place Gasketing Silicone Sealant/Adhesive

Self-leveling allows substantial savings in labor cost over the use of regular sealants due to the elimination of tooling


GasketingCSL537 is a one-part, moisture curing RTV (Room Temperature Vulcanizing) self-leveling 100% silicone sealant that cures to form a strong, low-modulus silicone rubber that maintains long-term durability and flexibility.

CSL537 remains permanently flexible and provides excellent resistance to weathering, moisture, vibration, ozone, ultraviolet and temperature extremes.

CSL537 has a broad temperature range of -60°C to 200°C (-76°F to 392°F).

Features & Benefits:
• Low viscosity, self-leveling requires no tooling
• Neutral cure formulation is ideally suited for use in confined areas since no objectionable odors are emitted. Non-corrosive
• Excellent unprimed adhesion to most substrates

CSL537 is available in grey.


CSL537 is designed for general industrial use where a self-leveling sealant/adhesive of a lower viscosity is required or in applications where a free-flowing, self-leveling silicone sealant is specified.
