| Abstract: |
| Several durable and anticorrosive coatings were evaluated using DMA in order to investingate the properties variation of these coatings during the stress. The relationship between modulus and temperature as well as tanδ－T were studied. DMA investigations revealed that structures and formation had a great influence on the mechanical properties and the chemical agent resistance of coatings. The results indicate that different characteristic properties can be compared to using DMA: the more uniformly cross-linked polyurethane coating and epoxy coating provided the best chemical agent resistance, the poor uniformly cross-linked polyurethane coating provided the best mechanical properties. |
