Industrial Park, Wacker’s Nanjing site
manufactures VAE dispersions and dispersible polymer powders for the construction, coatings and adhesives sectors,
as well as for a variety of other industries.
Wacker’s backward-integrated polymer
production not only ensures reliable raw
material supply for dispersible polymer
powders, but also enables synergies and
economies of scale through a common infrastructure and energy supply.
60,000 metric tons annually, depending
on product mix.
“After the successful capacity expan-
sion for vinyl acetate-ethylene (VAE)
copolymer dispersions in Nanjing site
earlier this year, we are now ready to
increase our dispersible polymer pow-
der capacity as well,” said Arno von der
Eltz, president of Wacker Polymers. “The
market demand in China is continually
growing, in particular for residential con-
struction. The increasing trend towards
construction of pre-decorated housing is
also driving demand for ceramic tile ad-
hesives, which require high-quality dis-
persible polymer powders. This capacity
expansion will support market growth
and strengthen our position as the lead-
ing manufacturer of dispersible polymer
powders in China.”
“It is integrated in our existing pro-
duction operations for isocyanates and
designed for the manufacture of both
raw materials,” said Hanno Brümmer,
head of Production and Technology
in the Coatings, Adhesives,
Specialties Business Unit at
Bayer MaterialScience. “Its mod-
ern equipment also is a response
to the demands of customers for faster
and more flexible delivery.” The company
invested some € 35 million in the expan-
sion project.
Bayer to Expand Production
Capacity of HDI & IPDI
Coating Raw Materials
The rising demand for polyurethane automotive coatings has prompted Bayer
MaterialScience to expand the production
of two important coating raw materials:
hexamethylene diisocyanate (HDI) and
isophorone diisocyanate (IPDI). After a
construction phase of a year and a half, the
company has now commissioned the multipurpose plant at Chempark Leverkusen.
It is also in line with Bayer
MaterialScience’s new sustainability concept, the aim of which is to increase value-added for the benefit of society, thereby
enhancing the quality of life. The raw materials produced in the new plant fulfill this
requirement in that they support the production of performance automotive coatings with good durability and resistance.
HDI and IPDI are also used in industrial coatings and adhesives.
