Abstract
A microcapsule is disposed in a self-healing coating having zinc powder particles dispersed therein. The microcapsule includes at least a silane coupling agent encapsulated within a volume defined by a metallic or polymeric shell that is rupturable responsive to formation of a fissure in the self-healing coating.
Claims18
A microcapsule disposed in a self-healing coating including zinc powder particles dispersed therein along with the microcapsule, the microcapsule comprising at least a silane coupling agent encapsulated within a volume defined by one of a polymeric shell and a metallic shell that is rupturable responsive to formation of a fissure in the self-healing coating.
A self-healing coating composition comprising:
- one or more film-forming binders;
- a plurality of microcapsules, the microcapsules comprising at least a silane coupling agent encapsulated within a volume defined by one of a polymeric shell and a metallic shell that is rupturable responsive to formation of a fissure in the self-healing coating composition;
- and
- zinc powder particles.
A coated article comprising:
- a metal substrate;
- and
- a self-healing coating adjacent the substrate, the self-healing coating comprising:
- a plurality of microcapsules, the microcapsules comprising at least a silane coupling agent encapsulated within a volume defined by one of a polymeric shell and a metallic shell that is rupturable responsive to formation of a fissure in the self-healing coating;
- and
- zinc powder particles.
