In this article, we report on the evaluation of microcapsule-based self-healing functionality in a range of organic zinc-rich primers with a view towards assessing potential synergies between the maintenance of the coating's adhesion to the substrate after damage afforded by the incorporation of the self-healing additive.

Self-healing polymers are a class of smart materials that have the capability of autonomically repairing themselves after damage, without the need for detection or repair by manual intervention.
