Most commonly used application methods:
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.
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.
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
Application of all APS chemical grafting
formulations can applied at ambient temperatures
and normal atmospheric conditions
Understanding the molecular structure
and nature of organic and inorganic
materials is the key to APS' scientists
sucesses. Our chemists detailed

APS' unique chemical grafting process results in properties being
permanently attached to the substrate with the use of a specialized
substrate activator and monomer system. Following are the most
