of those beans to make them more resistant to pests and pesticides. In
addition, these bean are used to improve productivity by the hectare. So
much so that there are estimates according to which Brazilian crops will
increase by around 50 percent over the next 10 years, and the potential
for growth in soybean crops alone for the same period is estimated at 48
percent. Concerningtheapplicationof theseoils, thoseadvances favor an
expansion of their application in various segments,” says Eduardo Oliva,
coordinator supplies and packaged products at UniAmerica.
When it comes tooil extraction technology, advances focuson improving
andpreservingthenatural propertiesof theproduct itself. “This increases
its applicability in end products and new developments and, as a result,
improves theutilizationof theseoils incoatings and resins,whichwindup
displaying better yields,” Oliva explains.
The fact is there is a trend in themarketplace towards replacingoil deriva-
tiveswith vegetableoils. “Theworld is becoming awareof this possibility.
In fact, this replacement has alreadybecome reality inEurope. Brazil is still
in its infancy in this respect, but it does keep advancing in research and
development.Manynaturalproductscandeliverthesameresultsaschemi-

Adhesion Promoters - Improved Adhesion
to Any Substrate
New developments in adhesion promoters focus on
the use of more sustainable, environment-friendlier
rawmaterials.
The Brazilianmarket for adhesion promoters, as is the
case in all other market segments, follows the global
market trend towards developing low-VOC products
at high concentrations and with lower environmental
impacts. In addition, users constantly seek products
that will deliver better performance and benefits like
UV protection, high-solids formulations and a more
efficient adhesion to any kind of substrates and in the
most varied of paint types.
Many are the efforts to bring into the marketplace
increasingly harmless and sustainable products. “The
development of technologies and raw materials that
pose less harm to the environment is an irreversible
trend which is part of the day-to-day business at large
companies. Evonik is really focused on these issues,”
remarks Sergio Brito, sales manager for the Tego line
of Evonik’s Coatings &Additives business.
The ongoing search of efficiency, whether in manu-
facturing or in the application of coatings, combined
withthe reductionofmaintenancedowntimes,makes
consumers more demanding about choosing their
adhesionpromoters, as they focus on the durability of
their coated structures. “As far as new developments
inadhesionpromoters go,we realize this issue ismore
andmore tiedupwiththesearchof corrosion inhibitor
properties. The trend towards DTM (direct-to-metal)
applications also seems irreversible. The associated
productivity improvements and energy savings justify
investments inmoreadvancedcoating technologies,”
saysLuisArnoldoCartheryJunior,businessmanagerat
Lubrizol’s PCG business in Latin America.
There is awide variety of adhesion promoter systems,
and some of the variableswhichdetermine the choice
of given process include the type of substrate, the
limitations of the application, and the applicable regu-
lations. “Eastman offers several products for this pur-
pose, from sucrose derivatives for use in nail polishes,
to polyester resins for application on flexible films, to
acrylicmonomers for decorativepaints, and to the line
of polyolefins for various difficult materials, such as
plastics, glass and aluminum,” says Eastman’s market
developmentmanagerforLatinAmericaAurélioBasso.
