Dispex Ultra PX 4275 is suitable for air and oven-dried coatings. Since Dispex® Ultra PX 4275 has no effect on pot-life it is recommended for aqueous 2 pack PUR coating. This ingredient has a low foaming tendency and to the best of our knowledge has no negative influence on the water and corrosion resistance. It is used in combination with zinc oxide, an increase of viscosity may occur. storage stability is to be checked.

Applications for DISPEX Ultra PX 4275

Dispex Ultra PX 4275 is an excellent wetting and dispersing agent for aqueous, binder, and solvent-free pigment pastes. By using this ingredient the optimum pigment stabilization can be achieved, this also applies to highly loaded pigment pastes. This product also gives outstanding flow properties to these systems. Dispex Ultra PX 4275 is also suitable as a wetting and dispersing agent for high-quality aqueous coatings based on different binders especially emulsions and dispersions. It impacts excellent wetting properties to both inorganic and organic pigments as a high gloss level and color strength are easily achieved. There are excellent rub-out properties even with critical pigment combinations.
