The First Coating Technology in the World that Simultaneously Reduces VOC and CO2 Emissions

3.Revamping the Undercoating Process and Using Water Based Paints to Achieve the Ultimate Three Layer Wet Paint System

Response to Mazda's unique Three Layer Wet Paint system technology has been sizable, and numerous domestic and overseas automobile manufacturers have come to inspect the factory. In addition, through a capital tie-up, Ford Motor Corporation is investigating the feasibility of introducing this technology to its plants worldwide. With its additional benefits in terms of reduced environmental impact, and improved product value and productivity, the Three Layer Wet Paint System may well become the international standard for the whole automotive industry.
This pioneering technological development has been awarded the Environment Minister's Prize, the METI (Ministry of Economy, Trade and Industry) Minister's Prize and various other awards. Currently, Mazda is conducting new research and development to further improve this internationally commended technology. The R&D has two major focuses. One is upgrading the process to reduce energy consumption during the initial electrodeposited anticorrosive coating process; and the other is developing "low-energy aqueous Three Layer Wet Paint System technology" for the application of water based paint to make the entire procedure even more environmentally friendly.
Mazda has developed a state-of-the-art technology that may well become the international standard for vehicle coating; the process which is currently the greatest obstacle to environmentally friendly automobile production. We will continue to pursue the ideal of a single solution to all the issues facing the coating process.

The Mazda Three Layer Wet Paint System Is a Combination of Coating Technologies

The Three Layer Wet Paint System is a combination of diverse technologies including production process design, paint composition, coating equipment design and of course coating technology. We coordinated the targets of the internal departments and paint manufacturers so we could all work in accord towards the ultimate goal.
The widespread adoption of the Three Layer Wet Paint System technology is desirable from the standpoint of the global environment. However, it is not a simple technology that can be introduced merely by supplying the right paints. We have to make the technological information as accessible as possible if we want to broaden its application throughout the industry.

The Latest Paint Compositions Born from Upgraded Processes

The paints for the Three Layer Wet Paint System have been developed from the latest paint composition designs, employing resins to prevent mixing between the first and second layers and adding components to improve the physical properties of the paint mix. Surmounting each difficulty has brought a sense of achievement, and we have now jointly applied for a patent for our new product. This kind of thing makes you glad to be an engineer.
We shall continue working on maintaining or improving the basic functions of automotive paints, and developing ever more environmentally friendly products.

The Satisfaction of Participating in a World-leading Project

Achieving the extremely precise specifications of paint composition necessary for the wet application of different types of paints was an extremely difficult development challenge. However, it was a privilege to participate in this pioneering joint project. It propelled our company's rheology (paint fluidity) technologies, achieving interfacial control between the first and second layers, and brought us the satisfaction of attaining paint characteristics that surpass those of conventional paints.
We look forward both to driving our environmental technologies onward and to building mutually beneficial relationships.
