CSL315 Self-leveling Silicone Concrete Joint Sealant

Ideally suited for concrete and as traffic loop sealant, crack filling, bridge expansion joint sealant and saw-cut control joint sealant. Self leveling, no tooling is required.


Concret CCSL315 is a one-part, neutral moisture cure, room temperature vulcanizing (RTV) 100% silicone sealant that cures to a low durometer.

CSL315 is self-leveling thus tooling is not required.

CSL315 exhibits excellent unprimed adhesion to concrete, steel and most other construction substrates, provided they are clean, dry and free of dust and frost.

CSL315 has good flexibility so it will maintain its integrity on joints with movement.

CSL315 is unaffected by sunlight (ultra-violet rays), ozone, temperature extremes, rain and snow.

CSL315 has a long service life, under normal conditions it will maintain its physical properties between -60°C to 200°C (-76°F to 392°F).
