The "Aqua-tech" coating system not only maintains the world's lowest CO2 emissions achieved by the "ThreeLayer Wet Paint System" coating technology currently used in all factories in Mazda Japan, but also further reduces VOC emissions by 57%. , The VOC emissions per unit area of ​​the body are controlled at 15g per square meter, making this technology the highest level of environmental protection for global waterborne coatings. At the same time, the quality of the products using this coating technology also exceeded the previous level.
Coatings that are generally water-based coatings have a low VOC content and are very effective in reducing VOC emissions compared to solvent-based coatings. However, the water used as a diluent in water-based coating consumes a large amount of energy in the process of evaporation and drying, resulting in an increase in CO2 emissions, which has long been a core problem that cannot be overcome by water-based coating technology. Mazda effectively solved this problem with new and innovative technologies.
Specifically, Mazda first improved the air conditioning system in the paint shop and introduced a high-efficiency evaporation system to promote the rapid evaporation of moisture in the paint. Based on this, a new type of high-performance coating was developed. The functions of color development, durability, and crack resistance achieved through the use of primers or middle coats were changed to the outer coating, and the process was optimized. . Through these technological breakthroughs, Mazda has successfully developed an innovative "Aqua-tech" water-based coating technology that drastically reduces VOC emissions without increasing CO2 emissions.
In the future, Mazda will use the Zoom-Zoom Sustainability Manifesto for forward-looking technology development to speed up the practical application of new technologies, commit to building the world's cleanest and environmentally friendly production facilities, and continue to provide consumers with driving pleasure and environmental protection. Safe and harmonious high-quality models.
Mazda Motor Co., Ltd. (hereinafter referred to as "Mazda") recently announced that it has successfully developed a new water-based coating technology, "Aqua-tech" coating system, and it has been put into use at Japan's head office, the Ulead First Plant. It is reported that this innovative technology can control the CO2 emissions brought about by the volatile organic compounds (hereinafter referred to as VOC: Volatile Organic Compounds) and the energy consumption in the coating process at the lowest level in the world.
