Heavy duty vapor barrier sealing for sheet metal, flexible, and fiberglass duct systems.
APPLICATIONS
- Aluminum Foil Backing provides a vapor barrier from moisture, contamination or corrosion.
- Acts as a heat shield, minimizing heat transfer.
- Superior conformability to adhere to irregular surfaces.
- Acrylic Adhesive System developed for solvent resistance and clean removal from surfaces.
- High adhesion – adheres tightly without lifting.
- Excellent aging resistance with long-term bond performance.
