Mazda's Aqua-tech Paint System is Reducing Environmental Impact
Mazda’s newly developed Aqua-tech Paint System
17th June, 2009
Mazda Motor Corporation has announced the successful
launch of the newly developed Aqua-tech Paint System for vehicle body painting at its Ujina Plant
No.1 in Japan. The innovative new technology achieves the world’s highest standards for limiting
emissions of volatile organic compounds (VOC) contained in paint as well as carbon dioxide (CO2) gas
generated from the energy consumed during the vehicle painting process.
The Aqua-tech Paint System maintains the same world-class low CO2 emissions volume as the Three
Layer Wet Paint System — Mazda’s paint system currently installed at all of its production facilities
in Japan — and reduces VOC emissions by a further 57 per cent. At only 15 grammes per square metre of
vehicle body surface, the extremely low VOC emissions volume makes Aqua-tech the least polluting
water-based paint system in the world. The new system also delivers improved paint quality.
Water-based paints tend to produce far lower VOC emissions than solvent-based paints due to their
low VOC content. However, drying water-based paint consumes much more energy because the water must be
evaporated through a drying process. The large amounts of carbon dioxide produced during this process
have long been an issue associated with water-based paint systems. Mazda has solved this problem with
the introduction of this new, innovative coating technology.
The Aqua-tech technology includes the introduction of an improved paint shop air conditioning system
and a new, highly efficient evaporation system that removes the water contained in the paint. In
addition, Mazda has managed to consolidate the coating processes by developing highly functional top coat
paints that exhibit additional properties usually provided by the primer paint. These include brightness,
durability and resistance to chipping and light damage. As a result of these technical breakthroughs,
Mazda’s Aqua-tech achieves extremely low VOC emissions without increasing CO2 volume.
Going forward, Mazda will continue to advance new technologies based on its long-term vision for
technology development. With cutting-edge production facilities that include the paint shop with the
smallest environmental impact in the world, Mazda is committed to producing vehicles that offer driving
pleasure in harmony with environmental and safety features.
The Ujina Plant No.1, one of Mazda’s main vehicle manufacturing facilities, is located near Mazda’s
headquarters in Hiroshima.
