All Weather Aluminum Foil Tape

MT-A7757 is a high strength multi-purpose aluminum foil tape used to primarily seal and seam a wide range of construction and building materials. It is coated with a superior performance flame retardant cold weather acrylic adhesive, and conforms well to surfaces providing a strong bond. This adhesive tape offers good reliability across both high and low temperature ranges. The paper release liner protects the adhesive from contaminants when the tape needs to be cut to specific lengths for use in tight spaces ensuring a strong bond once applied.
