Tri-Directional Reinforced Backing
3M™ Venture Tape™ FSK Facing Tape 1525CW is a 5.5 mil tri-directional reinforced tape that excels in demanding temperature and humidity applications. It is comprised of a foil/scrim/kaft laminated backing coated with a cold weather acrylic adhesive. This backing is flexible and conforms well to irregular surfaces and curves. With superior resistance to weathering, mold, UV and environmental conditions, this tape performs extremely well in demanding cold and hot temperature applications. It applies easily to both fibrous and sheet metal ductwork and is easily installed without special tools or application methods.
3M™ Venture Tape™ FSK Facing Tape 1525CW is UL723 Classified (10/10 Flame/Smoke Rating). The facing meets ASTM C1136 type II and IV.

- Vapor seal for reinforced aluminum faced fiberglass or mineral wool thermal insulation
Ultimate in Cold Weather Tapes
3M™ Venture Tape™ FSK Facing Tape 1525CW is coated with a pressure sensitive, cold weather solvent acrylic adhesive specifically designed for cold weather applications, though this adhesive performs well at normal and high temperatures as well. This adhesive features a quick stick at normal temperatures and superior low temperature performance. With a service temperature ranging from -40°F/-40°C to 240°F/116°C, this tape can be applied in a variety of environmental conditions. Once bonded, it will provide good holding power for extended periods with good aging properties that resist lifting and curling.
