Conventional coatings adhere to materials by simple mechanical
forces which can be easily broken causing peeling or delamination.
Such is not the case with chemical grafting since the attachment of
the coating is accomplished by forming a covalent bond between the
substrate and the monomers via the substrate activator. The chemical
reaction that takes place provides subsurface penetration in addition
to the chemical bond. As a result, much thinner coatings can be
obtained while providing longer life and superior performance of the
material.
Typical coating methods can be used i.e. dip, spray, roll. The
chemical grafting formulation comes in contact with the surface of the
substrate by any of these methods, The chemical grafting reaction
occurs instantaneously upon contact with the material. The desired
thickness and preferred application method will determine the
viscosity of the formulation. Most formulations are water based. The
coatings can be air dried, however, heat (oven, IR, UV, etc.) may be
used to accelerate the drying time. Most formulations will dry in
seconds to minutes.


In certain instances, the manufacturer wishes to compound the
modification into the raw material in bulk form. Sometimes it is
desirable for the substrate activator and monomer system to be
incorporated into the matrix of the substrate. The formulation is to be
blended with the pellets or resin and will be adjusted to the
manufacturers' extruding or molding process.
These plastic additives typically add on approximately 1-5% to
resin. In this case, the chemical grafting reaction takes place when
heat is introduced during the extruding or molding process. Besides
the introduced modification, there is no effect on the material or the
existing processing parameters.

Plastic Adhesives

Sometimes two or more layers of various materials are laminated
together to achieve desired characteristics. A generic adhesive used
for all purpose applications may fail especially when temperature
changes occur. Again, these conventional adhesives hold their
substrates together by mechanical means. In addition, failure of the
bond will occur during temperature fluctuations due to differences in
coefficients of thermal expansion. The adhesives developed by APS
use difunctional monomers and attach themselves to the substrates
by a
helical bond. This helix allows the resultant bond to move with the
differences in the expansion and contraction rates of the substrates.
Even substrates that are typically difficult to bond are activated and
attached by this means.

Grafted Properties
Oxygen/moisture, barrier, chemical resistance,
UV/ozone resistance, increased structural
strength, nonflammability/low smoke emission,
adhesion to inks/paints or other materials,
bactericidal, etc
These properties can be added to the
plastic
resin
or applied as a coating.

Our Specialized Services
Each project is treated on an individual basis
by formulating the desired plastic coating, plastic additive or
adhesive according to specific requirements.
Because of its easy adaptation to a wide
variety of applications, chemical grafting has
been utilized in virtually every industry
including automotive, aerospace, industrial
machinery, consumer products, medical,
packaging, and many others. In order to
obtain the chemically bonded product, new
formulation are applied to the submitted
substrate and tested according to the
recommended procedures dictated by industry
standards and manufacturer's requests. Once
reproducible results are secured, the
formulation is adapted to large-scale
production at the manufacturer's location. To
provide ongoing support, APS can
manufacture the final formulation in the
desired quantities and supply the
manufacturer with a pre-mixed, ready to use
coating, additive or adhesive.

The Mechanism of Chemical Grafting

APS substrate activators have the unique
capacity of removing active hydrogens from
substrates and initiating the growth of polymer
chains at that site. By removing these
hydrogens, an electron is removed forming a
free radical. This free radical site needs an
electron to stabilize its state and will share the
electron with the present monomers forming
the chemical bond. Following represents the
four step reaction of APS' chemical grafting
process using M to represent a metal
substrate (carbon steel, stainless steel,
copper, bronze, brass, etc.):

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
special formulation ingredient so that all
reactive components are exhausted.
