Extreme Sealing Tape
4412N
Technical Data September, 2010
Product Description 3M™ Extreme Sealing Tape 4412N is a single coated, pressure sensitive adhesive
tape 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 long term, 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
overlap layers of this tape can be used and still provide a tight seam to itself and the
joint or seam to be sealed.
