Static surface tension is a measurement of wetting and spreading ability on the solid surface at a balanced surface tension. Lower value of static surface tension,
higher performance of wetting and spreading.

Dynamic surface tension(DST) measured by bubble tensiometer is a symbolic application data of additive activity in paint, which means the ability of additive
dissemination from liquid to paint surface. Lower value of DST, higher speed of leveling.
