MINIMAL VOC EMISSIONS
The EU Solvent Emission Directive 1999/13/EC (SED)
has imposed a strict limit of less than five tonnes of solvents
emitted annually into the atmosphere for any customer
- in force since October 2007
* All waterborne paints supplied by HEMPEL are FREE of lead and chromates.

WATERBORNE ADVANTAGES
LONG LASTING PROTECTION
SEVEn yEarS LatEr…
StiLL aS nEwLy PaintEd!!
A 7 year inspection report shows that HEMPEL waterborne
products have stood up to all challenges and
proves that they offer outstanding protection to all
metal structures. GENSTAR, one of the biggest container
leasing companies in the world over the past
decade, requested waterborne products for its containers.
HEMPEL supplied HEMUDUR ZINC 18560,
HEMUDUR 18500 AND HEMUCRYL 58030 for an application
in India, under tough conditions. GENSTAR
Before
was impressed with the gloss of the topcoat, but also
the coating performance, which was performing on
par or better than the solvent borne system.
An inspection of the containers 7 years later proved
the long lasting protection offered by HEMPEL’s waterborne
products. The overall appearance was still very
good with high gloss. The pictures below act as the
best evidence.

SAFE & HEALTHY
WORKING ENVIRONMENT
By using waterborne coatings you can further obtain:
Reduced exposure to solvents for all people working with waterborne paints
Elimination of explosion and fire hazards
Electricians & welders can work close to the paint area
Other activities in the vicinity can proceed without being affected by the paint application (eg. in
commercial buildings)
All tools can easily be cleaned with water from the tap
Water is used for dilution
Lower insurance rates can be obtained

ALFA LAVAL
During the last five years, HEMPEL Sweden has secured a
world-wide Key Supplier Agreement with Alfa Laval, one of the
biggest global producers of heat exchangers. Alfa
Laval requests paints that are compliant to the
strictest VOC-regulations and suitable for their
fast 24-hour online production. HEMPEL meets
these demanding requirements by supplying
fast drying waterborne products. Since 2002
HEMPEL has supplied more than 123.000 litres
of waterborne epoxy coatings.
HELLENIC PETRELEuM
WATERBORNE CASE STORIES
WAGONY SWIDNICA
In 2002, Hellenic Petreleum S.A., the biggest Greek refinery,
built a new polypropylene plant in Thessaloniki, the
first of its kind in the Balkan region. This large-scale project
was based on an EXXON specification, requiring application
of waterborne products to areas such as piping,
tanks, spheres, steel constructions etc. HEMPEL (Hellas)
was chosen as the most suitable coating partner and supplied
approximately 110.000 litres of waterborne paints.
All structural steel and tanks were externally protected by
water-borne acrylics, whereas high temperature piping was
coated using water-borne inorganic zinc silicate.
One of the biggest cargo railcar producers in Poland, Wagony
Swidnica, and HEMPEL Poland have been closely cooperating
for many years on a number of projects, such as rail cars for
wood transportation, coal wagons and tank
car projects. Strict environmental regulations
and the request for high quality, certificates
and fast production, led Wagony Swidnica
to use waterborne coatings in 2003. Since
2003, HEMPEL Poland has met all their requirements
and has steadily been supplying
Wagony Swidnica with one, two and threecoat
waterborne systems or hybrid systems,
together with advanced technical service
support.
WATERBORNE REFERENCES
HEMPEL has more than 20 years of experience with waterborne paints. These
coatings have been applied on a worldwide scale for various applications, such
as bridges, windmills, rail cars, gas storage tanks, pipework installations, heat
exchangers, etc.
