If you manufacture a product which
contains polycarbonate and are looking
to increase the UV resistance of your
product  in order to give you a
competitive edge then contact  
Advanced Polymer Solutions regarding
our patented
Chemical Grafting.
We will develop a customized  
formulation based upon your UV
resistance specifications. Once we
develop and throughly test the
formulation it will become your property
which can be patented under your name.
APS can
manufacture the final

uv_resistance polycarbonate
formulation in the desired quantities and supply the manufacturer with a pre-mixed, ready to use coating, additive or
adhesive.
UV resistance on polycarbonate formulation can be added to the resin or developed as a coating.
UV stabilizers are added to polycarbonate to help protect the material from the effects of exposure to the Sun. Radiation
from the Sun, especially in the UV portion of the spectrum, degrades the properties of polycarbonate.
A material that is considered suitable for outdoor use has gone through testing in accordance with UL 746C, the
Standard for Safety of Polymeric Materials -- Use in Electrical Equipment Evaluations, of ultraviolet (UV) light exposure
for 720 hours of twin-enclosed carbon or 1,000 hours of xenon-arc weatherometer conditioning, and/or water exposure
or immersion for the seven days at 70 degrees C. The material is tested before and after exposure to these conditions
for flammability, mechanical impact and mechanical strength.

The results may lead to one of the following outcomes:

(f1) -- Suitable for outdoor use with respect to exposure to ultraviolet light, water exposure and immersion in
accordance with UL 746C. The (f1) footnote indicates that the material has met both UV and water exposure or
immersion requirements as called out in UL 746C.

(f2) -- Subjected to one or more of the following tests: UV, water exposure or immersion in accordance with UL 746C,
where the acceptability for outdoor use is to be determined by UL.The (f2) footnote indicates that the material has only
met or has been tested partially for UV or water exposure or immersion.

Application Methods

Most commonly used application methods:

Coatings
Coatings are applied on the surface of substrates to
improve the functional properties and durability.
Conventional coatings need extensive surface
preparation for adhesion and need to build up
thickness for performance. Such is not the case with
APS' coating formulations. Most APS coatings can
be applied in one step with no or minimal surface
preparation. In addition, due to the chemistry of
APS' chemical grafting process, thinner coatings
can be used to achieve a higher degree of property
performance. Delamination will not occur due to the
chemical bond formed between the coating and the
substrate with some subsurface penetration
occuring through the use of molecularly small and
lightweight monomers.

Typical coating methods can be used such as dip,
spray, roll, flow coat, etc. APS coatings can be
formulated to be air dried, however, in the interest of
time, heat or some energy source (i.e., UV or
infrared lights) can be used.

Additives
APS can develop additives to incorporate into the
raw material/resin prior to extruding or molding. In
this case, the new properties will penetrate the
matrix of the material. APS chemists will adjust the
formulation to conform to the processing parameters
used by the manufacturer. Due to the molecular
bond formed by APS' process, the new properties
will not migrate and leach from the material over
time, even under severe conditions.

Laminates (Adhesives)
APS chemists have extensive experience in bonding
the same or different substrates together. Materials
that are difficult to adhere to are effectively bonded
with APS' process. Again, no or minimal surface
chemical attachment of one substrate to the other.
Consequently, substrate failure will occur before
adhesion failure. In addition, if two substrates with
different coefficients of thermal expansion are
bonded, an APS developed adhesive's bonding
action will not be affected. Such is not the case with
conventional adhesives which cannot withstand the
varying expansion and contraction of different
substrates.

Application of all APS chemical grafting formulations
can applied at ambient temperatures and normal
atmospheric conditions
The Mechanism of Chemical Grafting

Advanced Polymer Solutions substrate activators
have the unique capacity of removing active
hydrogens from substrates and initiating the growth
of polymer chains at the site. By removing these
hydrogens an electron is removed forming a free
radical. This free radical site needs an electron to
stabilize its site and will share the electron with the
present monomers forming the chemical bond. The
following represents the four step chemical grafting
process:

1)        Activation: free radical formation
substrate activator
MOH_________  MC*


2)        Chemical Bonding of monomers:
MO
(CH2 — CH)n
x        x = functional group that changes with
each monomer and determines the property


3)        Formation of small polymer side chains: n =
controlled
chain length of monomers (same or varied)


4)        The reaction is then terminated with a
specific formulation ingredient so that all reactive
components are
exhausted.

Our monomers can be added to the resin or
developed as a
coating.

Frequently Asked Questions

Can Chemical Grafting impart desirable properties of an
expensive plastic onto a less expensive plastic?
Yes, the less expensive would then have the properties of a
more expensive plastic resulting in tremendous cost
saving.

Can Chemical Grafting work on any substrate?
No, although we have a vast array of activation monomers,
they cannot activate every substrate. Email us @
info@advancedpolymersolutions.com for a complete list of
substrates which cannot be grafted.

Can my company patent the formulation once it is
developed?
Yes, you will own the formulation, we will assist in
obtaining your patent.

Are the formulations safe?
Yes, The ingredients in all APS formulations will be
completely safe, can be water based in many cases, and
will conform to OSHA, EPA and, if required, FDA guidelines.

Can a chemically grafted formulation be used to attach
two different types of plastic?
Yes, in this case two different types of monomers will be
used to activate the substrate. This application would be
used as a coating between the two substrates.

Can the formulation be added to ink?
Yes to improve adhesion to various substrates, glass,
textiles, etc. Also to impart desirable properties into the ink
such as scratch resistance.

Once developed can Advanced Polymer Solutions
manufacture the coating or additive?
Yes, we can manufacture the formulation in any amount to
meet your requirements.

When grafting onto metals is any heat source required?
No, our activation monomers will bond to the metal forming
a covalent bond.
