HYDROPALAT® WE 3221 shows strong reduction of surface tension in water based systems. Therefore, it is highly suitable to improve substrate wetting and to prevent surface defects. It is recommended as an anti-crater additive with good recoatability. Furthermore, it can be used in UV-curable formulations to improve flow and leveling.

Based on a short chain organically modified polysiloxane, HYDROPALAT WE 3221 does not increase slip surface.
