PAT-ADD DA 103

PAT-ADD DA 103 by Patcham FZC is anionic polyelectrolyte, sodium salt. It is 45% solids polymeric dispersing agent for inorganic pigments in water. It enables high pigment loading in the mill-base, is non-foaming and contributes to best paint storage stability. It is strongly adsorbed onto inorganic pigments and extenders, thus creating a dense charged layer, which contributes to electrostatic stabilisation of the dispersed pigment and extender particles. The tendency of pigment flocculation, during paint production, storage or application is reduced, whereas properties like viscosity stability on storage, color development, opacity, scrub-resistance are being optimised, using PAT-ADD DA 103. Its benefits include reduced pigment grinding time and no phase separation. The optimal amount of PAT-ADD DA 103 to be used is system related, but generally is between 0.4 and 2.0% calculated on the total weight of the mill-base and 0.3-0.7% on total paint formulation. It is a REACH compliant grade.
