Coating photodegradation exposure time

It has been suggested that the decrease in the S parameter on exposure time is a result of the decrease in the defect (free volume) size or concentration due to irradiation [30]. This is a result of a net increase in the cross-linking density of the samples as a result of photodegradation. It has been demonstrated that there is a direct relationship between the decrease in the S parameter (loss of free volume) and an increase in the cross-linking density due to degradation for polyurethane coatings [32], We can postulate... [Pg.293]
