摘要
Effects of the natural degradation of protective organic coatings after exposure for some years in an industrial atmosphere (Turin, Italy) and the consequences of artificial weathering in an ultraviolet (UV) chamber (ASTM G 53) and salt spray test chamber (ASTM B 117) were compared using electrochemical, infrared, and calorimetric techniques. The comparison showed some differences between natural and accelerated weathering in the degradation mechanisms and provided information regarding future developments for new testing procedures.
