Résumé : |
A new test method for weatherability prediction using a remote plasma reactor has been studied. The degradation mechanism was studied, focusing on the fact that the exposure to radicals strongly influences the durability of coatings. As a means of radical irradiation on the coatings, a plasma-generating machine was used. More specifically, the weatherability of enamel-type coatings, surface changes (3D-SEM observations), as well as changes in colour and gloss, were studied using a down-flow-type machine (remote plasma reactor). The polarity index was also defined.
This remote plasma method correlated very well with the outdoor exposure test in addition, the acceleration behaviour with the test time was well controlled. |
