Self Healing Paint Compositions

Self-healing hydrophobic self-cleaning paint that combines biomimetic hydrophobic surface properties with self-repair functionality. The paint contains microcapsules that absorb water and undergo controlled degradation through a controlled release mechanism. When scratched, the microcapsules rupture, releasing the surface energy to reform the hydrophobic film. This self-repair mechanism enables the paint to maintain its hydrophobic properties even after physical damage or chemical exposure. The paint exhibits exceptional durability and chemical resistance, including salt spray and weathering resistance, and maintains its gloss level even after prolonged exposure.
