An article on how optically active coatings can shed light on the health of seawater ballast tanks. Published in Marine Technology in July 2018
The role of a coating is to protect the steel structure of a vessel from corrosion. Corrosion weakens the steel and leads to failure through cracking. The coating itself can also suffer from cracking due to over application or lack of elasticity. Therefore, there is a need to be able to detect cracks in either the coating or the steel as early as possible. The use of an optically active additive (OAA) in a coating system helps to identify cracks earlier. To read the full article download the PDF below.
