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