1933 can strongly reduce surface tension, provide excellent substrate wetting and prevent shrinkage holes. It can greatly enhance surface smoothness and substrate wettability in water-based, solvent-based coatings and ink systems, UV systems, etc. It also can significantly improve fluidity. It has good recoatability, and can improve scratch resistance and anti-adhesion performance. Meanwhile, it has high efficiency, high compatibility (minimize risk of fogging). It has little effect on interlayer adhesion and can  provide smooth hand feel for leather topcoats.
