Viper Double Bond Butyl Tape - 2” x 90’

Viper Double Bond Tape is a double-sided tape incorporating an exceptionally high tack, high peel, butyl adhesive system. Viper Double Bond Tape has a high adhesive mass that creates excellent gap filling and water-resistant properties. Viper Double Bond Tape is designed for sealing applications requiring an adhesive surface on both sides. Viper Double Bond Tape can be used as a self-sealing gasket, replacing messy caulks. It is ideal for sealing vapor barrier seams and adhering vapor barriers to vertical foundation walls and piers. Viper Double Bond Tape adheres aggressively to rough or porous surfaces.
