Abstract
Polymer coatings are widely used to protect high-quality and corrosion-sensitive surfaces against atmospheric loading. The protective properties of such coatings are largely dependent on their resistance to temperature fluctuations, water and UV light. The protective resistance of polymer coatings can be characterised by outdoor weathering, but this is a time-consuming process, so testing techniques that lead to an accelerated ageing of the coatings are increasingly being used to speed up the testing and development process. This article presents three new test methods that allow a rapid quantitative evaluation to be made of the protective resistance of polymer coatings to the loading parameters temperature fluctuations, water and UV light.
