SF 685 ShurMASTIC Butyl Foil Tape

The non-flammable butyl adhesive bonds permanently to the substrate, staying supple instead of hardening or cracking with age. It stretches significantly under stress without tearing, so it conforms fully around joints, seams, and irregular duct shapes. This creates an airtight, water-resistant seal that holds up in temperatures as high as 200°F.

Once applied, the tape accepts paint recommended for aluminum surfaces, letting installers match seals to surrounding ductwork for a clean, finished look. It contains no asbestos, CFCs, or PCBs, meeting standard environmental compliance requirements.

HVAC contractors and duct installation crews across the UAE use this tape where a permanent, code-compliant seal matters most, including outdoor and below-grade installations that face heat, moisture, and pressure over the long term.
