New Construction Application: Extend Protection and Prevent Corrosion with Self-Healing

Case Study | Supplied by Autonomic materials

Corrosion is a primary cause of failure for steel constructions. A common way to protect the assets against corrosion consists of metallic powder pigments, usually zinc-based, with an electrochemical potential that is higher than that of steel.

Such particles create an electrically conductive net, which acts as cathode protection: they oxidize at the place of the protected substrate and when their resource is exhausted, the substrate can be cleaned and re-painted again. However, cracks form due to the atmospheric deterioration and oxidative zinc depletion. So, how can we prolong the service life of protective coatings?
