Since paint sludge, one of the industrial wastes, is tacky and generated in a large volume in mass production vehicle painting shops, handling and disposal are very difficult.
We have this time succeeded in recycling this sludge as lightweight filler of vinyl chloride plastisol for coating underfloor (popularly called as under-body coating material) through thermal setting, crushing and pulverization after making it completely detackified and dewatered with centrifuging.
