Procedure
Leveling Test Procedure
- Draw the paint to be tested over a plane substrate (test chart), producing 5 pairs of streaks of various film thicknesses
- Hold the test panel in a horizontal position, and observe which of the pairs of streaks converge
- Generally, the gap depth of that pair of streaks is indicated, where the intervals between the streaks are slightly visible
Sagging Test Procedure
- Apply the coating, forming 10 streaks of various thicknesses
- Immediately after application, place the test panel into a vertical position, with the thinnest film streak at the top, avoiding any shock
- Depending on the sagging tendency the separate streaks converge
- For a reproduction of the results, which is difficult anyway, it is important to work under constant climatic conditions, to apply film streaks uniformly, and to set a time for evaluation
