Product Description

AFT50A Aluminum Foil Tape is coated with a pressure-sensitive solvent-based acrylic adhesive (underside of tape looks like uncolored silver aluminum foil). The tape comes on a white paper release liner. The tape features a malleable foil which conforms well to irregular and curves surfaces. Its aggressive adhesive provides quick, positive grab.

AFT50A is an all-weather general purpose used in fiberglass duct board systems (on seams and joints to maintain the integrity of the vapor barrier) and on FSK systems. Tape performs well at both low and elevated temperatures and is flame retardant. Used in the construction industry for joining elastomeric insulation systems.

The surface to which the tape is applied should be clean, dry and free of any grease or oil.
