The Best Bond

While there are several adhesive systems used on window films today, only one is developed and made exclusively for window film by the world's best adhesive innovator, 3M Company. Scotchtint Window Film uses a unique pressure sensitive adhesive with over 25 years of performance success unmatched by any other adhesive system.

The truth is that window film is only as good as the adhesive behind it. The long-term clarity of window film rests primarily in the adhesive, the bond between the film and glass. With that in mind, perhaps the following can help distinguish the good from the very best.

Pressure Sensitive Adhesives (PSA):

PSA's are common, but not by any means all the same. Unlike 3M's PSA, many are not as durable and temperature resistant. They tend to develop distortion from thermal cycling and have field failures, such as adhesive bubbling and blistering all resulting in lower visual quality.

Water Activated Adhesives:

In response to some of the PSA “clarity shortcomings”, water activated adhesives are used. Water activated adhesives chemically bond to the glass when activated by a solution. While they improve long-term visual quality, they too fall short in performance. First, this adhesive type is essentially permanent, making it very costly to remove. And second, the water activated chemical bond adhesives do not offer the shatter resistant benefits that PSA's do. Water activated adhesives often lack the shock absorption needed to resist glass shattering.

Fortunately, there is an adhesive that combines the best of these adhesive systems used in the industry today. Long-term visual clarity, removability and shatter resistance! All from one adhesive. All from one company. Scotchtint Window Film from 3M.
