Abstract
A coating for an article includes coating encapsulated micro-spheres which maintain the coating in a fluid state. The coating encapsulated micro-spheres are retained in the coating to form a matrix of hardened coating and coating encapsulated micro-spheres. Damage to the coating form a fissure which breaks open the coating encapsulated micro-spheres adjacent the fissure. The broken coating encapsulated micro-spheres release the fluid coating material contained therein. Because the coating encapsulated micro-spheres release the encapsulated coating material in the fluid state the coating material flows into the fissure to coat the exposed substrate. This provides a “self-healing” ability to the coating which protects the substrate even after the coating is damaged.
