Waterborne and powder coatings or to replace traditional solvent

Automotive coating production lines produce large amounts of paint using a solvent such as VOC,and heavy metals.European automotive coating with coating technology to replace painting,painting maximize the use of water-based and powder coatings,far below the European emission regulations.Some advanced automotive coating production line further proposed the concept of zero-VOC emissions.

According to experts,because along with the global demand for environmentally friendly coatings have become increasingly demanding,more environmentally friendly water-based paints and powder coatings market has become the most popular products,including the global trend of environmental protection requirements for powder coatings is to promote the development of a major driving force,because manufacturers are looking for ways to reduce VOC, powder coating in some areas so natural alternative to liquid coatings.Low VOC powder coatings,clear easily,paint overspray recyclable;construction substantially no pinholes after coating,generally easy to work with than the liquid paint,the formed coating film durability.Environmental and technological advantages of powder coating alternative to traditional solvent-based coatings key.Waterborne automotive coatings and powder coatings to become the darling of the market on the other hand,water-based coatings are eyeing,in recent years,volatile organic compounds paint for the environment and the human body has attracted much attention,and waterborne coatings compared to conventional solvent-based coatings can greatly reduce VOC emissions,which can effectively reduce the impact on the environment, but also helps to reduce the probability of occupational diseases of the potential to reduce fire risks and storage problems,to simplify and reduce air,water and other aspects of the processes and costs,etc.All this demand are water-based paint has laid a certain foundation.

"After 2010,with the Chinese rail vehicle products gradually enter the international market,some foreign customers,especially in developed countries,users have demanded the vehicle using water-based paint coating is projected that in 2020,the domestic rail passenger cars,buses and suburban railway in our country manufactured in the territory of international rail vehicles will reach nearly 80,000, greater demand for coatings present this part of the market share of 81,267 tons solvent-based paints,thinners 23,424 tons,accounted for only 12.3% water-based paint,the market has great potential."Changchun Railway Vehicles Co., Ltd.Senior Engineer Hao Bo said.In 2007 the company's first light rail car used in two-component epoxy primer,two-component polyurethane paint,polyurethane finish, and other water-based paint for vehicle painting,to achieve the desired effect. According to experts,China's paint brands want to break through the layers of strong competitors to enter the ranks of the world rankings,or take some time and effort.In China,more environmentally friendly water-based paint or powder coatings and will replace the traditional solvent-based coatings status,the future seems promising.
