Dispex® Ultra FA 4437
Non-ionic wetting and dispersing agent for aqueous formulations; especially designed for organic pigment concentrates.
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 Dispex Ultra FA 4437 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, Dispex Ultra FA 4437 has a strong affinity to pigment surfaces thereby reducing color acceptance problems.
