Clear, Tough Plastic Tape
Compatible with Most Cold-Applied Sealants
Use CRL Bond Breaker Tape to create proper two-way sealant bonds. A clear, tough plastic tape with a clear polyethylene adhesive backing, it is eight mils (.2 millimeters) thick and has high adhesion to steel or other structural metals. It is important for sealant to bond to joints in two places so it can expand properly. If the sealant bonds in the wrong areas, it may tear or stretch to the point of failure.

Width of Tape: 1 in (25 mm)
Feet per Roll: 108 ft (33 m)
For Sealing Shallow Joints
Bond Breaker Tape is applied to the bottom of the joint so the sealant will bond only to the walls.
For Metal Butt Joints
Bond Breaker Tape is applied to metal edges so the sealant can be "buttered" over the joint and can properly expand or contract.
