PAT-ADD DA 501

PAT-ADD DA 501 by PATCHAM FZC is an APEO-free non-ionic polymeric wetting and dispersing agent. It is most effective for organic pigments. It 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. It is free of carboxylic or other charged anchoring groups. Optimizes color development. Possesses strong prevention of pigment flocculation, floating, flooding, and pigment settling. Used in a wide range of waterborne industrial paints, such as acrylics, stoving systems, 2-pack systems, epoxies, polyesters etc. The optimal amount of PAT-ADD DA 501 to be used is system related, but generally is between 0.5 and 2.0%, calculated on the total weight of paint formulation. 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. It is a REACH compliant.
