No.1 New Challenges Under the Water-based Paint Replacement: The “Repulsion Effect” Between Polymers and Coatings
Traditional solvent-based paints, due to their severe VOC emissions, can no longer meet the environmental requirements of regulations such as the EU REACH Regulation. The automotive interior coating process is rapidly transitioning to water-based paints. However, while water-based paints offer significant environmental advantages, they expose a critical flaw—these polymers (e.g., ABS, PP, commonly used in automotive interiors) have low surface energy, resulting in poor wettability and insufficient adhesion of water-based paints. This can lead to issues such as coating delamination and reduced weather resistance. Particularly for irregularly shaped interior components (e.g., curved dashboards, 3D door trim strips), conventional surface treatment methods struggle to achieve uniform modification, further reducing production yield.
No.2 Zhenhua’s Innovative Solution: Reshaping Material Surface Properties, Empowering Water-based Paint Coating
Addressing this industry pain point, Zhenhua Vacuum has independently developed vacuum Plastic part nitrogen fluorination treatment equipment, helping automotive component manufacturers overcome the bottleneck of insufficient water-based paint adhesion and providing efficient, eco-friendly pre-coating treatment solutions.
Equipment Advantages:
