Development of Eco-friendly new coating technology

摘要

It is very important to decrease the amount of environmentally hazardous material in automotive industry because environmental protection is internationally focused on. In automotive mass-production plants, Because paint processes emit environmentally hazardous material, such as Volatile Organic Compounds (VOC) and CO{sub}2, consumed for air-conditioning and baking, measures against them are essential. A large amount of VOC can be reduced with conventional Eco-friendly technology, such as water-base paints, which caused increases in CO{sub}2 and production cost. Therefore, Eco-friendly technology, having quality more than conventional coating and significantly reducing VOC and CO{sub}2, was developed and introduced into Hofu plant in July, 2002. This technology is called "Three-Layer Wet Paint System" for all-inclusive environmental measures by integrating primer process with topcoat process. This technology materializes a level under the average of European VOC regulations, and CO{sub}2 reduction more than a conventional method by more than 15%.
