What is the impact of UV exposure on marine materials in relation to corrosion?

The impact of UV exposure on marine materials is significant, particularly concerning protective coatings that are designed to prevent corrosion. When ultraviolet (UV) radiation from the sun interacts with these coatings, it can lead to their degradation over time. This degradation may result in a breakdown of the coating's integrity, diminishing its ability to protect the underlying material from environmental elements such as moisture and saltwater.

As protective coatings suffer from UV degradation, they become less effective at preventing oxidation and other forms of corrosion on the substrate they are meant to protect. This ultimately increases the risk of corrosion, as exposed areas become vulnerable to the corrosive effects of the marine environment. Therefore, it is crucial for vessel maintenance strategies to include consideration of UV exposure and the regular inspection and maintenance of protective coatings to ensure they remain effective over time.
