Sample chemical resistance is to scale from the gloss retention：
C4Level：8h ± 30min of acid or alkali erosion, gloss retention in more than 80% (allowing a 60% to 80%).
C3Level：After 8h ± 30 minutes, acid and alkali erosion 1h ± 5min, gloss retention of 60% to 80%.
C2Level：After 8h ± 30 minutes, alkali and 1h ± 5min acid erosion, gloss retention of 60% to 80%.
C1Level：After 8h ± 30min of acid or alkali erosion, gloss degree of retention rate below 60%.
