All Weather FSK (Foil/Scrim/Kraft) Insulation Facing Tape

FS-K7751 is an adhesive tape used to primarily seal foil faced insulation such as FSK faced fiberglass ductboard and blanket systems installed by mechanical insulation contractors. It is coated with a high performance, flame retardant cold weather acrylic adhesive that does well in low temperatures and provides a strong bond to a variety of surfaces and textures. The epoxy resin coating helps protect the surface against corrosion from moisture. The paper liner protects the adhesive from contaminants when you need to cut the tape to specific lengths ensuring a strong bond once applied. This tape is UL 723 Classified and mold resistant.
