Abstract: In this paper, using the analytical conclusion of Fick rule, the absorbing moisture process of abrasion adhesion coating material is measured. Furthermore, the dynamic absorbing moisture consistency and stress of applied coating are analyzed. The results show that the absorbing moisture property of coating is affected by the filling quantity and curing dose; the maximum absorbing moisture consistency is about 4%; relative to the initial strength, the dynamic absorbing moisture stress of coating is a small quantity.
