3M Extreme Sealing Tape 4411N Translucent 2 in x 36 yd 40 mil

3M 4411 Extreme Sealing Tape is a highly conformable single-side acrylic tape with a high-performance ionomer backing which is 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 used in 3M 4411 is designed to adhere well to the ionomer film so that overlapping tape joints can be made while maintaining a strong seal. The tape gives you consistent thickness over using a liquid adhesive. Used for motorhome leaks roof and gutter holes/tears and the transportation industry. Comes on a release liner on the non-adhesive side to allow for easier unwind. Please note the translucent color is almost white because of the thickness of the tape. Features and Benefits Sticks on contact to many metals and plastics without drying time dripping oozing and clean up Excellent high-pressure water moisture and thermal shock resistance Durable Clear appearance and paintable Made in the U.S.Application Instructions It is often required to overlap 3M Extreme Sealing Tape onto itself. In this case the ionomer backing of the first piece is one of the substrates to which the second piece of tape is bonding. The tapes should overlap at least 3/4 inch. The ionomer does not need to be cleaned prior to bonding unless it has been contaminated with oil dirt grease etc. If the bonding area of the ionomer has been contaminated IPA/water can be used to clean the surface. A quick wipe of 3M 111 Adhesion Promoter on the ionomer is suggested for best performance of the overlapping tape. AP111 will approximately double Extreme Sealing Tape’s adhesion to its own ionomer backing. Firm pressure should be applied to all points of overlap between the two tapes to join the adhesives and create a robust seal.
