UV Degradation

Definition - What does UV Degradation mean?

UV degradation refers to the cracking or disintegration of materials exposed to ultraviolet radiation, most commonly due to sunlight exposure. The absorption of ultraviolet radiation energy from the sun stores enough energy within the molecular bonds of the material to cause disintegration of the intermolecular bonds holding the structure together.

Corrosionpedia explains UV Degradation

UV degradation is widely observed in materials located outdoors for their primary purpose such as above-ground pipelines, surface storage tanks and other structures that have a prolonged exposure to sunlight and other elements.

UV degradation and damage can be prevented by reducing sunlight exposure times and providing housing units for materials prone to UV degradation.
