BASF is the only coatings manufacturer to operate its own whirling arm test equipment to measure rain erosion on fast rotating leading edges up to 500km/h. This means all products are thoroughly evaluated before introduction and provide many times more in service life than standard coatings. BASF also tests all its coatings for UV resistance, flexibility and other important characteristics.
