Abstract: | Method for determination of internal stresses influence on durability of powder paint coatings is developed. The method is based on the difference ofthermal-oxidative degradation activation energy of cross ЕD-linked film-forming material within loose and metal-bedded film. It is shown that powder paint coatings internal stresses are insignificant as metal-bedded cross-linked film-forming material does not take big deformations of coatings in the process of their formation as well as during the usage. Reduction of thermal-oxidative degradation activation energy of the parameter ЕDwith such internal stresses is only 3–7 kJ/mol and it does not reduce the coatings durability much in comparison with the influence of the factor of the climatic chamber of UV radiation and high temperatures. |
