Abstract
This study investigates self-healing coatings for scratch-resistant car paint, focusing on their effectiveness in restoring
surface integrity. Experiments were conducted using polyurethane-based coatings infused with microcapsules containing healing
agents. Coated samples were subjected to controlled scratches of 100–500 μm in width, and healing efficiency was analyzed
through optical microscopy and surface roughness measurements. Results showed that coatings with 10 wt% microcapsules
exhibited an average healing efficiency of 85% within 24 hours, compared to 40% for those with 5 wt%. Additionally, Nano
indentation tests indicated a 30% improvement in hardness. These findings highlight the potential of self-healing coatings for
enhancing automotive paint durability.
