DESCRIPTION
|
A high quality solvent-release duct sealant made from a blend of rubber, fillers and polymers. 795 Sealant is a plastic sealant as defined in BS6213:1982 “Selection of Construction Sealants”. Grey in colour. |
USES |
For sealing seams and joints in duct work. |
CURE |
Cures by release of solvent. An initial skin forms within 4 hours, no curing reaction occurs. When all solvent has been released the material remains inert and very pliable. |
JOINT DESIGN |
795 Sealant has been designed for use in bedding joints. The performance therefore depends on the degree of movement and the joint clearance. |
|
For movement joints, a joint clearance of 3mm is recommended with a sealant width (w) of 12mm. When used for bedding then a thin section can be used. |
