Question

How is automotive going to water base paint instead of stulvent base paint eco friendly?

Answer 1

By using water-based paint instead of oil-based paint, we cut volatile organic compounds (VOC) by 70% (120g/㎡→35g/㎡). And unlike traditional coating which requires three drying processes, water-based paint requires only two, thereby reducing greenhouse gas (CO2) emissions by 15%.  

Of course, this eco-friendly process also has its share of problems. Due to its property of dissolving well in water, an increase in waste water treatment costs and COD (Chemical Oxygen Demand) is inevitable with water-based point. Nevertheless, we are tirelessly seeking ways to resolve these issues.

Some people worry whether using water-based paint would make the coating job more difficult. Others are concerned that the paint dissolves in water or that water may seep into the paint after the coating process. But there is no need to worry. Water-based paint is easy to work with and once the paint dries, its waterproof membrane capability, very similar to oil-based paint, helps to protect the paint job from water.
