Our tape was specifically designed to give you professional results under outdoor exposure to direct sunlight, as well as temperature and humidity extremes while creating an effective seal over an existing joint, seam, or penetration.
Stick a variety of metals and plastics with 3M™ Extreme Sealing Tape 4411N. Our durable, highly conformable, single-side acrylic tape is designed for difficult sealing applications such as joints, seams or penetration. It sticks on contact without drying time, oozing, and mess. It has excellent sealing properties and good outdoor resilience. When applied it has a clean appearance and can be painted on. The backing of our tape is an ionomer film which is tough, flexible and abrasion resistant. The adhesive is designed to stick to the ionomer film so that overlapping tape joints can be made while maintaining a strong seal.
