Self-healing coatings are advanced materials designed to repair themselves when damaged. These coatings contain microcapsules filled with healing agents that release upon cracking or scratching. When the coating is compromised, the healing agents flow to the damaged area, solidifying and restoring the coating's integrity. These coatings are used in various applications, including automotive finishes, electronics, and building materials. By extending the lifespan of surfaces and reducing maintenance costs, self-healing coatings offer significant benefits in durability and performance, making them an innovative solution in material science.
