Evaluation of easy-to-clean coatings – Beyond contact angle measurement
The demand for displays in automotive applications is rapidly growing. Simultaneously, anti-finger-print and easy-to-clean solutions are getting more important to ensure an enjoyable usage of theses devices. A smooth feel as well as a good cleanability are fundamental properties for high quality display applications. The company COTEC GmbH offers coating technologies comprising machinery and easy-to-clean coating materials for such surfaces. A set of methods to evaluate and to compare such functional surfaces will be presented. While most of the current judgements are only based on contact angle measurements, mainly against water, a measurement method is presented which allows an application-oriented evaluation of such coatings. This study is presenting procedures for standardized measurements for soiling and cleaning of a surface, software-based analysis of the results and a objective comparison of different display surfaces. These methods show directly the applicability for touch displays in an automotive interior environment. A reproducible simulation of soiling and cleaning as well as a rating of the smoothness based on physical data is providing a method for a reliable choice of appropriate components. Integration of automated measurements and software-based analysis is representing the possibility to create standardized processes for evaluation, comparison and selection of easy-to-clean display surfaces.
