Robust Polishing - Evaluation of the polishability of coated surfaces

Important results from the project

The project was primarily aimed at creating a deeper understanding of the polishability of current and future coating materials. Through increased knowledge, we wanted to lay the ground for future development of standardized methods for assessing the polishability of coatings. We have: -Developed an equipment and method for repeatable testing of polishability of coatings -Evaluated different methods for assessment of polishing defects and succeeded in quantifying defects -Built knowledge of the parameters that affect the polishability and the appearance of polishing defects

Expected long term effects

The project has given increased understanding of the parameters that are most important when polishing defects occurs. It is expected that acquired knowledge will lead to continued development of methods for assessment of polishing defects. This, in turn, can simplify the development and introduction of new coatings, since the polishability of the coating can be verified at earlier stages. It is also expected that production personnel will be able to access the knowledge and gain greater understanding of the importance of properly performed polishing operations.

Approach and implementation

Volvo Car Corporation has been the main applicant and project leader for the project, the other parties being Halmstad Högskola, AB Volvo and Beckers. Most of the development work has been carried out at Halmstad Högskola but with regular alignment and dialogue with the industrial parties. Various practical attempts were made at the parties. The work plan has worked well and it has been successful workshops at all industrial parties and the university.
