What is Bond Breaker Tape?
Bond breaker tape is a specially designed tape that serves as a barrier between sealants and surfaces, preventing adhesion where it is not desired. This feature is particularly important in joint sealing applications where three-point adhesion can lead to joint failure. By ensuring that the sealant only bonds to the sides of the joint, bond breaker tape enhances the flexibility and performance of the sealant.
How Bond Breaker Tape Works
The functionality of bond breaker tape lies in its unique construction. Typically, it features a pressure-sensitive adhesive on one side and a bond-inhibiting material on the other. This arrangement allows the tape to adhere firmly to surfaces while preventing the sealant from sticking. The most common material used for this tape is polyethylene, which offers excellent conformability and durability, making it suitable for various surfaces, including irregular ones.
Key Applications of Bond Breaker Tape
1. Joint Sealing
One of the primary applications of bond breaker tape is in joint sealing. It is used in construction projects to create expansion joints, control joints, and other types of joints in concrete structures. By preventing three-point adhesion, it allows for proper joint movement and helps avoid cracking.
2. Waterproofing
Bond breaker tape is also critical in waterproofing applications. It ensures that sealants are applied correctly, maintaining the integrity of the waterproof barrier. This is especially important in areas prone to moisture exposure, where a reliable seal can prevent water infiltration.
3. General Construction
In general construction practices, bond breaker tape serves as a versatile solution for various sealing needs. It can be utilized in a wide range of projects, including residential and commercial buildings, where the durability and performance of sealants are paramount.
Choosing the Right Bond Breaker Tape
When selecting bond breaker tape, several factors should be considered:
Material
Most bond breaker tapes are made from polyethylene due to its excellent properties. However, some applications may require different materials for specific performance characteristics.
Width
Bond breaker tape comes in various widths, typically ranging from 1/4 to 4 inches. The choice of width should align with the dimensions of the joint being sealed.
Adhesive Type
Different tapes utilize various adhesive types, such as acrylic-based adhesives, which offer high adhesion and durability. It’s essential to choose a tape with an adhesive that suits your specific application needs.
