DuPont™ Tyvek® Butyl Tape

Product Code: RA6BTV

DuPont Tyvek® Butyl Tape is a butyl-based sealant designed specially for use with Tyvek® breather membranes or AirGuard® AVCLs.


This double-sided butyl tape is compatible with most common building materials and helps you achieve airtight and watertight seals that can also withstand humidity and chemicals.
Tyvek® Butyl Tape is most effective when used under compression – for example, under a timber batten. It is recommended for perimeters, chimneys and abutments, and also for sealing nail penetrations and around electrical sockets.

Feature Benefit
Forms a moisture-and-airtight seal
  • High resistance to water, humidity, environmental cycling and chemicals
High immediate tack
  • Strong adhesion to many different surfaces, where an acrylic Tape is not applicable (for sandy surfaces Tyvek® Primer is recommended)
