Verfahren
Sample preparation:
- Apply paint to black plastic panel with a wet film thickness of 3.5 mils and width of 150 mm
- Apply coating in 3-4s to prevent pin holes/holidays and cure for 7 days
Procedure:
- Measure reflectance CIE-Y (R1) of coating on last day of drying
- Apply soilants/stains in straight pairs of lines perpendicular
- Soak sponge in water and squeeze
- Apply liquid or powder cleaner
- Scrub for max. 100 cycles
- Measure reflectance CIE-Y (R2) of the soiled and washed area
- Calculate the reflectance recovery in percent as R2/R1 x 100
