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 – the 3M
Company. 3M
window film uses a unique pressure
sensitive adhesive with over
twenty-five 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. With that in
mind, perhaps the following
can help distinguish the good
from the very best.
Pressure Sensitive Adhesives
(PSA): PSAs are common, but
not by any means are they all
the same. Unlike 3M's
PSAs, 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.
Water Activated Adhesives: Water
activated adhesives are used
in response to some of the PSA
clarity shortcomings. These
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. Second,
water activated adhesives do
not offer the shatter-resistant
benefits that PSAs do as they
often lack the shock absorption
qualities needed to resist glass
shattering.
Fortunately, there is an adhesive
that combines the best performance
traits of the above two systems.
An adhesive that provides long-term
visual clarity, removability,
and shatter resistance is offered
by only one company – 3M.
