APS is located in Port Washington, New York occupying 10,000 square
feet of laboratory and production areas. Our facilities are fully equipped
with testing apparatus, homogenizer, centrifuge, mixer, extruder, coater,
industrial filter, UV system and salt spray chamber.
APS has fine-tuned a unique process of chemical grafting which allows
manufacturers to permanently add or improve the performance of a
material while retaining its existing characteristics. This process involves
substrate activation, and the attachment and polymerization of
monomers that contribute the desired properties (in this case corrosion
resistance) onto the backbone of the substrate using safe, effective
organic chemicals. Because a covalent bond is formed, the molecularly
bonded formulation is permanent and cannot be leached, even under
severe conditions.
Coatings are used to improve the functional properties of a substrate for
corrosion resistance, electrical conductivity, wear or abrasion resistance,
etc. Conventional coatings adhere to substrates 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 graft coatings is accomplished by forming a covalent bond
between the substrate and the monomers via the graft initiator. As a
result, much thinner coatings can be obtained while providing longer life
and superior adhesion of material. The chemical reaction that takes
place provides subsurface penetration and chemical bonding. Coating
thickness can be adjusted according to specification. Results have
proven that coatings of .5 mil thickness can provide a minimum of 500
hours

Metals
Corrosion Resistant Coating
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.

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

Our Specialized Services
Each project is treated on an individual basis by
formulating the desired coating, 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.
Metals are usually inclined to form cations through
electron loss, [6] reacting with oxygen in the air to form
oxides over various timescales (iron rusts over years,
while potassium burns in
seconds). Examples:
4 Na + O2 → 2 Na2O (sodium oxide)
2 Ca + O2 → 2 CaO (calcium oxide)
4 Al + 3 O2 → 2 Al2O3 (aluminium oxide).
The transition metals (such as iron, copper, zinc, and
nickel) are slower to oxidize because they form
passivating layer of oxide that protects the interior.
Others, like palladium, platinum and gold, do
not react with the atmosphere at all. Some metals form a
barrier layer of oxide on their surface which cannot be
penetrated by further oxygen molecules and thus retain
their shiny appearance and good conductivity for many
decades (like aluminium, magnesium, some steels, and
titanium). The oxides of metals are generally basic, as
opposed to those of nonmetals, which are acidic. Blatant
exceptions are largely oxides with very high oxidation
states such as CrO3, Mn2O7, and OsO4, which have
strictly acidic reactions.
Painting, anodizing or plating metals are good ways to
prevent their corrosion. However, a more reactive metal
in the electrochemical series must be chosen for coating,
especially when chipping of the coating is expected.
Water and the two metals form an electrochemical cell,
and if the coating is less reactive than the coatee, the
coating actually promotes corrosion
