Features & Benefits

Properties

Polymeric dispersant PAT-ADD DA 501 shows strong interacting and high bonding strength on a wide variety of substrates. The multifunctional anchoring moieties in the polymer enable strong adsorption even onto apolar surfaces, such as from organic pigments. Once adsorbed, PAT-ADD DA 501 molecules are unlikely to be desorbed, even on dilution conditions. These unique properties explain the excellent performance of PAT-ADD DA 501 if used in industrial paints and pigment concentrates. PAT-ADD DA 501 is free of carboxylic or other charged anchoring groups. PAT-ADD DA 501 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 501 is recommended for use as wetting and dispersing agents in high loaded resin-free or resin based pigment concentrates.

Dosage & Addition

The optimal amount of PAT-ADD DA 501 to be used is system related, but generally is between 0.5 and 2.0% PAT-ADD DA 501, calculated on the total weight of paint formulation. 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 10% PAT-ADD DA 501 on total weight of the PC. The optimum concentration to be used depends on the individual requirements and conditions.
