MT-A7729
All Weather White Aluminum Foil Tape

MT-A7729 is a high strength white aluminum foil tape used to primarily seal joints for foam core insulation boards.  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.
