440 Tape

Butyl Preformed Sealant Tape

Tremco 440 Tape is a 100 percent solid Polyisobutylene cross-linked butyl, preformed sealant. It is unaffected by UV through glass and remains flexible at low temperatures. A 6-inch (150mm) toe bead of compatible sealant at each corner is required to minimize potential for water infiltration.

Basic Uses

• Can be used for lap sealing between panels such as steel, aluminum and porcelain as well as a variety of other joints subject to shear between similar and dissimilar materials.
