| Résumé : |
In the paint and several other allied industries many methods and techniques have been developed to relate a flow quantity to a particular coating performance characteristics. Off the various physico-chemical properties studied in coating technology, rheology, a physical property play an important role in paint manufacturing. The knowledge of the rheology of materials and how to manipulate it through formulation is a vital tool in the optimization process. In addition to that, knowing about the various types of rheometer/viscometer, their conversion units, various factors on which it actually depends and its effect on different coating properties would be an added advantage. This review article discusses the concept of rheology, measurement and its application in surface coating. |
