Organic coatings are mainly used to protect metals from corrosion, but due to the influence of internal and external factors, the coatings will appear aging phenomena, such as decreased mechanical strength, reduced adhesion, discoloration, embrittlement, powdering, loss of luster, and Acid spots etc. As a result, the protective effect on the metal is lost. The article "Aging Mechanism and Influencing Factors of Organic Coatings in Atmospheric Environment" mainly analyzes the external environmental influencing factors of organic coatings, including sunlight, heat and temperature, water and humidity, oxygen and ozone, and pollutants. major environmental factors. The colleagues of the article also analyzed the different aging mechanisms of organic coatings in the atmospheric environment.
The final conclusion of the article shows that solar radiation, especially ultraviolet light, heat and temperature, water and humidity are the most important factors that cause the aging of polymer materials.
