Rubber
Adhesives for UHMW
Rubber based adhesive systems typically
offer the highest adhesion and shear properties in comparison
to acrylic
or silicone. They are best used in ambient, indoor applications
as rubber adhesives are susceptible to UV and elevated temperatures.
Since rubber adhesives are very aggressive, they will work with
a wide variety of substrates and satisfy most adhesion requirements.
Acrylic Adhesives for UHMW
Acrylic based adhesive
systems are more versatile than rubber based systems and
provide a host
of attributes such
as UV stability, higher temperature performance and good
to excellent chemical resistence. While rubber based adhesives
have a higher
initial bond, the acylics go through a 24 hour cure cycle
or “wet-out” period
where over time, the bond continues to improve. Acylic systems
are usually a little higher cost but offer longer life than
rubber adhesives.

Silicone
Adhesives for UHMW
Silicone based adhesive systems are primarily
used for application requiring very high temperature resistence
or
for applications where the adhesive will be bonding to a silicone
filled material. These sysems typically do not possess high adhesion
and would only be recommended for thin films where thermal expansion
or shear will not not be an issue. Silicone adhesives are also
high priced which may exclude them from competitive situations.
