Addressing Adhesion and Durability Challenges of Waterborne Coatings on Automotive Plastic Components
Application
Driven by automotive lightweighting trends and increasingly stringent environmental regulations, waterborne coating systems are rapidly replacing conventional solvent-based painting processes and are now widely applied to automotive interior plastic components.
However, plastic substrates typically exhibit low surface energy and complex geometries, which pose significant challenges to coating adhesion and long-term durability. Vacuum fluorination surface treatment technology has therefore emerged as a critical pretreatment process for waterborne coating applications on automotive plastic parts.
Customer Pain Points
Insufficient adhesion of waterborne coatings
Conventional surface treatments often fail to sufficiently increase surface wettability, leading to issues such as coating delamination and peeling.
Limited durability and consistency
Under long-term use and varying temperature and humidity conditions, coating stability on interior plastic components is difficult to maintain.
Non-uniform treatment of complex geometries
Components with complex contours, deep cavities, and intricate structures are prone to uneven surface modification, negatively affecting coating quality and production yield.
Zhenhua Vacuum Solution
Zhenhua Vacuum has developed a vacuum fluorination surface treatment system that modifies plastic surfaces through a controlled fluorination reaction.
Without compromising the intrinsic properties of the substrate, the process significantly enhances surface energy and chemical activity, providing a stable and reliable interface for subsequent waterborne coating processes. The solution is designed to meet the requirements of high-volume production with high consistency for automotive plastic components.
