Parchem Bond Breaker Tape is a high-quality polyethylene tape specifically engineered for isolating sealants. It effectively eliminates sealant adhesion to concrete, metals, and joint filler boards.
In professional joint sealing applications, this tape is essential for preventing "3-sided adhesion." By ensuring the sealant only bonds to the sides of the joint, it allows the material to stretch and compress properly to accommodate natural structural movement.
