electronic media in conducting business, our publishing company, BNP Media, is
branching out beyond print media, and is discovering a wealth of opportunities
for our customers with electronic media.
Montmorillonite is the main
constituent of bentonite and it is a smectite clay of worldwide distribution. Workers in the field have been trying to improve the miscibility of the clay in
polymers for more than 100 years.
With
today’s evolving technology, one thing to look for in a coatings additive is
multifunctionality. Multifunctionality allows paint formulators to achieve a
number of different benefits with just one product.
The
primary role of surfactants in emulsion polymerization is to lower the
interfacial tension, which allows the emulsification of reactive vinyl monomers
and the formation of stable colloidal dispersions of nano-size polymer
particles.
Besides
high efficiency, UV stabilizers have to meet some other basic, but most
important requirements. To grant such high efficiency, perfect compatibility,
that is excellent solubility in the film-forming binder, is a definite must.
The
utility of silicone-organic resin binder hybrid technology has enjoyed rapid
growth in the protective coatings markets. A wide array of chemistries and
applications provides opportunities for unique combinations and benefits to the
end-user.
Because
of environmental concerns, powder coatings, 100% UV/EB curing systems and
waterborne polymer dispersions are being substituted for traditional resins
used in solventborne coatings. Development in the area of polymeric dispersions
and radiation-curable materials is the main subject of this paper.
The biannual Nürnberg Congress, held in conjunction
with the European Coatings Show in May 2007, hit an all-time high in terms of
attendees, presentation quality, enthusiasm and a pervasive sense of R&D
excitement.
