Presentation How does it work? Self-healing mechanism in smart coatings: how does it work? High performance coatings with self-healing additives become smart coatings and the protective nature of the coating is re-established after damage to provide continuous substrate protection. What is the mechanism behind self-healing coatings? The self-healing process is truly autonomous and does not require external energy. The trigger is the damage! The process follows three main steps as described below: The microcapsules are ruptured by the damage itself Microencapsulated delivery of liquid healing agent to the site of damage Healing agent polymerizes and heals damage The healing is effective on all levels of coating degradation from small scale to large scale damage: Small-Scale Damage Large-Scale Damage Conditions Multiple internal microcracks Damage size < 50 um Impact shocks, weathering, etc. Damage size >= 500 um Edges sealed off Results Test Control vs Self-healing Impact test Scribe test Key benefits Applications
