- CASE Ingredients Features
- Excellent FlowFloating ResistanceImproved Rheology
PAT-ADD DA 440 is a polymeric dispersing agent for use in waterborne industrial paints, gloss dispersion paints, pigment dispersions and printing inks. PAT-ADD DA 440 is the most effective dispersant for the dispersion of inorganic and moderately polar pigments, including carbon blacks, in aqueous systems.

- Properties
Polymeric dispersant PAT-ADD DA 440 shows strong interacting and high bonding strength onto charged surfaces, such as from inorganic pigments and polar treated organic pigments. Once adsorbed the multi-functional PAT-ADD DA 440 molecules are unlikely to be desorbed, even on dilution conditions. These unique properties explain the excellent performance of PAT-ADD DA 440 if used in industrial paints and high loaded pigment concentrates. PAT-ADD DA 440 is designed for use in a wide range of waterborne industrial paints, such as acrylics, stoving systems, 2-pack systems, epoxies, polyesters etc. Moreover, PAT-ADD DA 440 is recommended for use as dispersing agent in high loaded, resin free pigment concentrates.

- Addition and Dosage
The optimal amount of PAT-ADD DA 440 to be used is system related, but generally is between 0.4 and 2.0% PAT-ADD DA 440, calculated on the total weight of paint formulation. The dosage is related to the offered pigment surface area, organic pigments and high surface carbon blacks being at the higher side of the recommendation. The product is best added to the mill-base before the pigments. For use in pigment concentrates (PC), higher levels are suggested, such as 3 to 8 % PAT-ADD DA 440 on total weight of the PC. The optimum concentration to be used depends on the individual requirements and conditions.
