3M Extreme Sealing Tape for Roof Sealing Application

3M Extreme Sealing Tape: 3M launches 3M™ Extreme Sealing Tape, 4412 N for roof sealing application, an unique and dependable product.

Increasingly, as every part of Construction Industry is leaning towards "Green" the roofing is moving towards more light transmittable material. What better way to conserve energy but to allow the natural light into your office, shop or residence through skylights? The famous architect Frank Lloyd Wright was known to light up the interior spaces with natural light and believed," the best way to light a home is nature's way". Exciting technological advancement has made it possible today to design roofing which allows daylight to come in minus the glare and at the same time conserve energy.

Skylights, which is supposed to bring light to your life, often do spring a leak and by the time it is diagnosed or even detected, they would have damaged, the ceiling or even form a puddle of water below. Typical causes of a leaking glass or polycarbonate roof is the inadequate flashings, loose capping or perished seals. Sealants can fix seals temporarily but it is never the answer. Another major cause of leakage, especially in the metal roofs is fastener movement. Thermal shocks causes fastener to loosen and back out.

3M launches for roof sealing application, an unique and dependable product – 3M™ Extreme Sealing Tape, 4412 N- a single coated, pressure sensitive adhesive sealing tape, designed for difficult sealing application. The backing on this tape is an ionomer film that is very tough yet flexible and yet abrasion resistant. The very soft and thick acrylic adhesive has excellent sealing properties and outstanding outdoor durability. This single coated tape is designed to seal over an existing joint, seam or penetration. The adhesive is designed to adhere well over the ionomer film to enable overlapping of the tape and yet provide a tight seam to itself and the joint or seam to be sealed.

The long term high temperature tolerance (days and weeks) of this sealing tape is 93° C ( 200° F) while the short term high temperature tolerance (minutes and hours) of this film is 149° C (300° F). The immersion resistance, temperature resistance, high humidity resistance and temperature cycling resistance of Extreme Sealing Tape is demonstrated as below :

Over 2000 hours of accelerated aging exposure of the tape indicated on cracking or chalking of the 3M™ Extreme Sealing Tape 4412 N. The sealing tape still had 10 pounds per inch width of peel adhesion strength.

The first step is to remove the existing sealant in the gap which was leaking as there may be entrapped water inside ( Fig 2). The surface has to be cleaned using Isopropyl alchohol and water (50 : 50). 3M™ Adhesion Promoter 111 was then applied on the cleaned surface where tape will be applied. The tape will then be applied over the joint with the non stretch liner in place from corner to corner ( Fig 3). With the non stretch liner still in place, the tape is to be pushed into the seam joint using a hard squeeze( fig 4). It will then be rolled down with a roller( fig 5)

The non stretch liner is to be removed by peeling from a corner. Once the liner is removed the tape shall appear flat in finish. If the liner remains, the finish will be glossy. The final roll down will be performed using a soft roller again using firm pressure. The entire operation can be completed in a day.
