Performance Enhancing Additives
Unimin: Unimin offers a complete selection of mineral filler additives for gloss
control, UV stability, flame and smoke
suppression, UV/EB cure synergy plus
transparency, and food packaging coatings. Global sales, distribution and manufacturing networks are in place.
CW: Given the added cost
associated with these types
of additives, what are the
benefits to the customer?
BASF: Light stabilizers are pivotal in any
coating systems always exposed to harsh
UV rays and other strong radiation from
sun. Light stabilizers help in preventing
gloss reduction, delamination and degradation of coatings over an extended period. They help in preventing the change
in color or yellowing of the coatings.
Customers who use light stabilizers benefit from increased quality of their products including maintaining aesthetics and
appearance of the coatings.
Borchers: Our unique dispersant technology provides a clear advantage in pigment
wetting, therefore providing higher jetness,
stronger color development, shorter grind
times and lower viscosity. This results in
a lower formulated and productive costs.
Our Borchi OXY-Coat products provide
a unique cobalt free drier alternative. It
delivers faster oxidative cure, better drying
in adverse conditions and much brighter
whites. It can be used in many different
types of applications, marine, general industrial and architectural.
Clariant: The benefits to the customer
are very much dependent on the individual additive and its application. The added
value of these types of additives can be
seen in many different aspects.
Cutting formulation complexity for
our customers is one of our aims. With
this in mind, our main focus lies on multi-functional performance and sustainability
advantages while providing specific guidance on the product functionality and use.
As a result of extensive internal profil-
ing of our wetting and dispersing agents
portfolio, we are able to provide very
concise information on additives’ various
functions at different processing stages,
suitability for different coating systems
and of course formulation benefits and
“side effects”. Providing one additive for
multiple applications and with multiple
benefits can lead to less ingredient use,
lower inventory, less logistics and less
costs – a big boost for any customer.
To take a different aspect, within the
coatings industry Clariant is well known
for the consistently high-quality ammo-
nium polyphosphate that can be used on
a wide range of materials (most impor-
tant of which is steel) for use in build-
ing structures. Clariant’s EXOLIT®
AP 422 ammonium polyphosphate for
intumescent coatings is considered as a
benchmark in the industry. Coatings in-
corporating these additives as acid do-
nors form foam chars in fire situations,
slowing down the transfer of heat to the
substrate and reducing loss of structural
integrity. Customers benefit from higher
performance levels like clearness, bright-
ness, smoothness, UV-stability, durability
under exposed conditions of coatings, or
simply from fulfilling building require-
ments like fire retardancy / fire resistance.
Clariant’s waxes from the
CERIDUST® and LICOWAX® lines help
to protect and beautify surfaces, provid-
ing excellent control over feel, texture
and gloss, and also serve as invaluable
aids in many processing steps. Customers
benefit from better haptic effects like
silk touch, better protection and easier
cleaning of wood products like furniture.
In addition, wax additives also have an
impact during the production of a coat-
ing. For example, by using CERIDUST®
9615 A, powder coating manufacturers
can offer coating solutions with opti-
mized protection properties in the cured
film in a car rim. Another example is
LICOWAX® PE 520, which can help
with the pigment dispersion in coatings
for bicycle frames. Adhesion properties
on the surface can also be adjusted. With
Clariant’s CERIDUST® 6050 M window
frame coatings have a better adhesion to
silicon sealants to ensure improved heat
transfer or insulation properties.
The performance additives from the
HOSTAVIN® and HOSTANOX® series
improve weathering resistance and re-
duce color fading and loss of gloss. These
benefits translate into longer lifetime of
the coatings, in maintaining the shining,
glossy effect longer and in delaying the
discoloration of the wood substrate or
color fading in automotive and architec-
tural coatings.
Dow Coating Materials: Performance
enhancing additives can help boost formulations to a new level, helping paints,
inks, and coatings stand out among the
competition. While there may be some
additional cost associated with the use of
these types of additives, the efficiencies
or performance enhancements they offer
outweigh the higher price point.
keim additec: Our additives help the
formulator balance and fine tune the
surface properties of their products.
Improvements can be achieved in; longer
life cycles, durability, surface protection/
modification like e.g. scratch resistance.
Lonza: Microbial control additives protect the value that the coating’s formulator builds into their formulation, and
they also protect the formulator’s reputation. Typically, the cost of the microbial control additive is small compared
to the value of the formulation, and so
the tradeoffs among microbial control
additives are more often about avoiding
undesirable impacts on the formulation.
For example, MIT is a commonly used
preservative ingredient, however it can
show up as a VOC, and this downside
might more than offset its benefit in the
preserved product formulation.
Micro Powders: Our additives are like
medicine in a coating. A customer needs
to use the correct additive to get the desired effect in their application, and we
“diagnose” surface performance challenges with our customers every day. In
addition, they should always optimize the
dosage level to use as little as is necessary
to achieve the surface modification they
need in their system.
Shamrock Technologies: Shamrock
Performance Additives provide specific
end properties such as slip control, mar
and abrasion resistance, matting, and
