Product

Description

3M™ Extreme Sealing Tape is a family of single coated, pressure sensitive adhesive tapes

designed for difficult sealing applications. The backing on this tape is an ionomer film that is

very tough yet flexible and abrasion resistant. The very soft and thick acrylic adhesive has

excellent sealing properties and good outdoor durability. This single coated tape is designed to

seal over an existing joint, seam, or penetration. The adhesive is designed to adhere well to the

ionomer film so that overlapping tape joints can be made while maintaining a strong seal.
