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 agents flow to the damaged area and solidify, restoring the coating's integrity and appearance. These coatings are used in various applications, including automotive, electronics, and construction, to enhance durability and longevity. By reducing the need for repairs and maintenance, self-healing coatings can lead to cost savings and improved performance in products, making them an innovative solution in material science.
