Photostabilizers, coatings

This symposium deals primarily with current studies on the science and technology of coatings photostabilization. Related topics also are included with the expectation that exposure to a related field may serve to inspire new insights into one s specific discipline. An international scope is provided with contributors from Canada, France, Great Britain, Switzerland, West Germany, and the United States. 

When the photostabilization of a polymer material is to be obtained through such a surface treatment process, it is all important to make sure that the protective effect will last throughout the service life and therefore to ensure a long-term adhesion of the coating onto the substrate. This can be best achieved by promoting a grafting reaction between the two elements (20). For that purpose, the photoinitiator was partly incorporated in the top layer of the PVC plate by a surface treatment with an acetone solution. Upon UV-irradiation of the resin-coated sample, the following reactions are expected to occur ...
