3M™ Extreme Sealing Tape 4412N is a family of single coated, pressure sensitive adhesive tapes designed for difficult sealing applications. 3M™ Extreme Sealing Tape features a backing that is constructed of an ionomer film that is very tough yet flexible and abrasion resistant.

The adhesive is designed to adhere well to the ionomer film so that overlapping tape joints can be made while maintaining a strong seal.
