Concrete Joint


CSL316 High Performance Self-Leveling Silicone Concrete Joint Sealant

CSL316 High Performance Self-Leveling Silicone Concrete Joint Sealant

Ideally suited for sealing horizontal joints in concrete where extreme movement is experienced.


Concret CCSL316 is a one-part, neutral moisture cure room temperature vulcanizing (RTV) 100% silicone sealant that cures to a low durometer and has high elongation but remains very durable.

CSL316 is self-leveling thus tooling is not required.

CSL316 exhibits excellent unprimed adhesion to concrete, steel and most other construction substrates, provided they are clean, dry and free of dust and frost.

CSL316 has good flexibility and a low modulus so it will maintain its integrity on joints with a high degree of movement.

CSL316 is unaffected by sunlight (ultra-violet rays), ozone, temperature extremes, rain and snow.

CSL316 has a long service life and maintains physical properties between -60°C to 200°C (-76°F to 392°F).

CSL316 is suitable for United States DOT’s applications.
