CoatOSil* silicone polyether additives are widely used in water-based and solvent-based, high-solid, powder, UV-curable coatings and inks and other fields.
Key features and typical advantages:
1. Enhance flow and leveling (eliminate pits, orange peel and other defects)
2. Better slipperiness (reduce friction coefficient)
3. Better scratch resistance
4. Bubble control and enhanced air release
5. Better substrate wettability
6. Higher gloss
7. Anti-adhesion (release)
