General
DISPEX® Ultra FA 4437 is a silicone-free surface-active flow additive and colour acceptance improver for aqueous systems based on emulsions and aqueous resins. Due to its good wetting properties the dispersing agent ensures better wetting of difficult-to-wet substrates. The emulsifying effect of this product also prevents surface defects such as craters, fisheyes, pinholes, and streaks caused by incompatible components. Furthermore, it has a strong affinity to pigment surfaces thereby reducing color acceptance problems.
