China
in China, put also into production its resin plant in the middle of 2014 to provide
high quality raw materials to its plants in
Tianjin and Anhui. With a new production base under construction in Shanghai,
Axalta Coating Systems announced recently that it will establish a joint venture
with Shanghai KLT to produce automotive coatings in the future.
With the local municipal governments
under huge public pressure to improvie
air quality, the automotive coatings in-
dustry has been required to reduce VOC
to a new level in recent two years. China’s
first painting line for water-based coat-
ings was put into operation in 2005. By
the end of 2010, there were ten painting
lines of water-based coatings. In 2015, it
is estimated there will be over 50 paint-
ing lines to use water-based coatings in
China. Although the water-based variet-
ies have been increasingly applied in in-
termediate coatings and color coatings,
the percentage is only around 30 percent,
The central government requires wa-
terborne varieties to be used in the new
paining lines build after 2012, a regula-
tion which has speeded up the water-based
coatings’ development in recent two years.
And more pressure originated from public
demand to improve the air quality in mu-
nicipal cities such as Beijing, Shanghai and
Guangzhou and Shenzhen has been felt by
all the industries, and automotive industry
is no exception. Guangdong has put into ef-
fect the limitation of VOC for the new build
or existing painting lines no less than 20g
per square meters. Tianjin has announced
on July 31st that the since January 1, 2016
the VOC limitation for the painting line
of the existing car producers should be
less than 45g per square meters, and the
VOC limitation for new build painting
line should be less than 35g per square me-
ters. Other car production centers such as
Choangqing, Beijing and Shenzhen all have
similar new regulations published or to be
published recently.
But the VOC of the car body painting
lines of most of the automotive producers
in China is above 100g per square meters, and these painting lines were built
at a time where there wasno strict regulation to limit VOC, so eliminating VOC
can not happen overnight in China. And
the Western automotive manufacturers
are leading the way in the painting line
transfer from solvent-based coatings to
water-based coatings. Huachen BMW
painting workshop, which was constructed by German Durr, has a VOC level at
2.3grams per square meters after putting
into operation. These best practices and
experience will be learned and shared by
other companies and push the automotive coatings application to a new level in
the future. With the efforts of the public,
government and producers together, the
automotive coatings market will soon become greener, and that’s for sure. CW
