VOC guideline - background information
VOC emissions
Volatile organic compounds (VOC) can be directly harmful to
human health and when combined with oxides of nitrogen and strong
sunlight they can contribute to the formation of ozone close to the
soil. In some countries in Europe, levels in excess of 50% of VOC
emissions can be reached in areas where solvents are used. The
paint industry has therefore made great efforts to reduce the
proportion of solvents and achieve a proportionate improvement by
increasing the solid matter content of the materials.
International legislation was required to implement potential
reduction processes in the paint processing industrial sector.
On 30.11.1999 the first draft concept was submitted to the paint
associations. Obligations were laid down to work to the best
technology available. The time scale of the EU Directive was laid
down as a stepped schedule starting in 2004 and initially defined
until 2007. The European VOC legislation is based on national VOC
legislation.
This naturally has a direct effect on
paint shops (painting of private cars). The following values apply
to existing installations after the date given. Compliance of
materials with a solid matter content (FK) on average:
Until 1992
|
25% FK
|
From October 2005
|
35% FK
|
From October 2005
|
45% FK
|
With the products brought together in the service supply range
and the adaptation of installations, reductions of up to 80% can be
achieved.
Suggestions for modifications to paint shops: install closed
spray cleaning plant. Use HVLP guns or application equipment with a
similarly high degree of effectiveness. Separate application and
cleaning systems for water-based paints or paints containing
solvents. Uncured waste paint must be disposed of separately.
Note: Using
water-based coatings is an appropriate method of reducing solvent
emissions and thus meeting environmental specifications. Our paint
partner will advise you on the jobs you need to do to convert to
using water-based coatings.
