Bayferrox high-performance pigments for most challenging
demands
Leverkusen - Specialty chemicals company LANXESS is
presenting its high performance pigments under the motto
"Sustainability and Technology" at ABRAFATI 2011, the main
Latin American scientific and business event in the
coatings industry, to be held in São Paulo, Brazil, from
November 21 - 23. The comprehensive product portfolio
includes in particular Bayferrox red shades for paint and
coating applications and yellow pigments with special
properties
With the high complexity of modern coating systems, the
demands on the coating raw materials are growing too.
LANXESS' range of high-performance pigments more than meets
the increasing requirements of the customers with respect
to maximum consistency of quality for color shade and
tinting strength, easy processability and reliability of
quality. According to Dr. Volker Schneider, head of the
Global Competence Center Paints at the Inorganic Pigments
business unit, "the decisive advantages of our
high-performance products are their tight tolerances with
respect to shade and tinting strength. This improves
quality consistency and makes formulation paints and
coatings faster, easier and more reliable; shading work is
reduced to a minimum." In addition, these pigments are
characterized by very good dispersibility. This is achieved
through micronization, a very intensive form of grinding,
that results in a significant reduction in the proportion
of pigment aggregates in the product.
The reds of the Bayferrox 100 line cover a very broad range
of color shades, extending from a yellowish cast to a
distinctly bluish shade. The special quality properties
achieved in the manufacturing of these high-performance
pigments is mainly due to the use of the Laux process. This
process lends the pigments their excellent heat resistance
and protects them from changes in the hue even when they
are subjected to intense milling, grinding or dispersion.
This is the reason for the widespread popularity of these
red pigments in nearly all temperature ranges relevant to
the paint and coatings industry. The excellent quality
consistency of these Bayferrox grades provides a reliable
basis for all customers whose products have to comply with
very tight and consistent color specifications over long
periods.
The high quality yellow pigments Bayferrox LOM produced in
Porto Feliz will be also presented during the tradeshow.
The LOM pigments have low oil absorption and are micronized
providing low viscosity. "The Bayferrox 912 LOM was
specially developed for highly filled pigment pastes.
Micronization ensures especially good dispersibility in
fast-moving dissolvers", added Giselle Martins, Coordinator
Global Competence Center for Latin America.
Customers in a wide variety of industries have been putting
their trust in Bayferrox pigments for 85 years. For
LANXESS, sustainability in production is extremely
important. The high grinding stability and consistency of
color quality achieved in the manufacture of these pigments
is due not least to the Laux process. This process has been
used in the world's largest production facility for
inorganic pigments at the company's site in
Krefeld-Uerdingen, Germany, since 1926. This method is
exemplary in its consistent use of the reaction heat
generated during the synthesis of the iron oxide pastes.
This heat is re-used for the production of steam and hot
water for subsequent process steps. The result is a process
whose energy efficiency is currently unsurpassed.
LANXESS is one of the world's leading manufacturers of
iron-oxide-based inorganic pigments. These have a track
record going back 85 years as components of paints and
coatings, plastics and paper, as well as for use as
specialty pigments for toners and other applications. "We
help our customers on technical issues through the services
we offer with our Global Competence Centers. And not least
we develop customized solutions for the demands of
tomorrow", said Schneider.
The IPG business unit belongs to LANXESS' Performance
Chemicals segment, which achieved total sales of EUR 2.0
billion in fiscal 2010.
