13. Performance tests – Test methods
Test Method
Samples stirred for 6 minutes@5000 rpm followed by measurement of weight and volume
Foam 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 wetted
Substrate 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, judgment
Anti-cratering
of craters after film drying
Automatic spray application on coil coated Al panels, dry film thickness at 30-35µm, measurement
Leveling
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
