1520CW Aluminum Foil Tape is a 2 mil, (50 micron) high strength aluminum foil tape coated with an aggressive, high temperature, acrylic adhesive system. The foil tape conforms well to both fibrous and sheet metal ducts, providing an excellent vapor seal. The malleable foil tape also conforms well around corners and to irregular surfaces. Coated with a special cold weather acrylic pressure sensitive adhesive system which combines superior quick stick at normal temperatures, as well as superior low temperature (below freezing) performance, this is the ultimate in cold weather foil tapes. Recommended to use at normal and elevated temperatures as well.
