Why do we have to change using solvent base paint into waterborne paint?

The use of waterborne paint instead of solvent-based paint is becoming increasingly common in the automotive industry due to several reasons:

1.Environmental concerns: Solvent-based paints contain high levels of volatile organic compounds (VOCs) that contribute to air pollution and have adverse health effects on humans. Waterborne paints contain lower levels of VOCs and are considered to be more environmentally friendly.

2.Regulations: Many countries have strict regulations on VOC emissions, and the use of solvent-based paints may not comply with these regulations. As a result, many automotive manufacturers are switching to waterborne paints to meet these regulations.

3.Improved performance: Waterborne paints have improved performance in several areas, including better adhesion, flexibility, and durability compared to solvent-based paints. Additionally, they have better color matching properties, resulting in more precise color matches, which is particularly important in the automotive industry.

4.Cost savings: While the initial cost of switching to waterborne paint may be higher due to equipment and training requirements, long-term cost savings can be achieved due to reduced material and labor costs, as well as lower disposal costs.

Overall, the switch from solvent-based paint to waterborne paint is driven by environmental concerns, regulations, improved performance, and cost savings. As a result, the use of waterborne paint is expected to continue to increase in the automotive industry in the coming years.
