  • 13. Performance tests – Test methodsTest Method Samples stirred for 6 minutes@5000 rpm followed by measurement of weight and volumeFoam behavior using a graduated cylinder Assessment 1: Wetting limits Spray application of an increasing film thickness (wedge) on coil coated Al panels, measurement of the lowest film thickness when the substrate is completely wettedSubstrate wetting Assessment 2: Wetting behavior on pretreated PE-foil Spiral coater application on pretreated PE-foil (solution of a release agent), assessment of wetting defects after film drying Post contamination of the formulations with mod. PDMS, spiral coater application on PE-foil, judgmentAnti-cratering of craters after film drying Automatic spray application on coil coated Al panels, dry film thickness at 30-35µm, measurementLeveling of w-values as well as LW/SW with wave-scan DOI Spiral coater application on e-coat panels, curing at relevant temperatures, humidity cabinet for 5 days,Intercoat adhesion after 1d at standard conditions cross-hatch adhesion test 13
