Questions |
| |
|
-
A. Nearly
all polymers except highly fluorinated materials
like Teflon can be treated for enhanced adhesion.
Additives, such as antioxidants and uv stabilizers,
can have a significant impact on how easily a given
material can be treated. Excellent results are achieved
with polyolefins (polyethylene and polypropylene),
PVC, acrylics,and polystyrene.
| Q. How
long will the treatment last? |
-
A. The
treatment is a permanent change of the surface .
| Q. How
does surface modification treatment affect
the performance of adhesives? |
-
A. Surface
modification enhances adhesion in two ways.
Firstly, treatment causes the formation of polar
functional
groups on the surface. These groups include
hydroxly and carboxyl groups. These polar groups
create a
high surface energy condition on the material.
This means that polar liquid such as epoxies, polyurethane
latex, and many other materials readily wet
the surface.
Secondly, as the adhesive or coating cures,
these surface functional groups can bond to the
coating
through covalent bonds or through hydrogen
bonds -
| Q. How
is this different from other adhesion-enhancing
surface treatments? |
A. The
permanent nature of the Fluoro-Seal treatment is
one of the factors that differentiates Fluoro-Seal's
treatment from other adhesion-enhancing treatments.
This is a result of the crosslinking of the surface-modified
polymer chains. Reactive gas modification can also
penetrate relatively deeply on a molecular basis,
which also promotes permanence.
| Q. What
if I have special requirements? |
A. If
you have special requirements, Fluoro-Seal will be
happy to work with you to design a Customer Specific
Quality Plan (CSQP) to meet your needs.
