Abstract

The decoration and protection quality of coatings on polymers is of considerable interest for industrial applications. However, at present there is no non-destructive (NDE) method to monitor the quality of these coatings during the manufacturing process or while they are in use. As an approach for such a method we use photothermal analysis where the propagation and reflection of optically generated thermal waves is investigated. We found that one can monitor the drying process, the effect of surface temperature treatment, and coating thickness (accuracy + 2 μm in 50 μm thickness). The information obtained with this remote NDE method is adequate for most industrial applications, eg car manufacturing.
