3M 4411 Extreme Sealing Tape [Discontinued]
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
- Clear appearance and paintable
Made in the U.S.
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.

Question & Answers
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
