Carlisle CCW-704 Mastic

Carlisle CCW-704 is a solvent-based, rubberized bitumen mastic. After evaporation of the solvent, the remaining compound is a rubber-like material that adheres tenaciously to the polyethylene facer of CCW Sheet Membranes.

CCW-704 Mastic is used as a secondary seal on the seams, T-joints, overlaps and other terminations/penetrations of CCW sheet membrane systems. It is designed for use on the top surface and edges of the CCW sheet membrane and should never be used underneath the membrane.
