PAT-ADD DA 301

PAT-ADD DA 301 by PATCHAM FZC is an anionic wetting agent and compatibiliser. It shows extreme strong wetting efficiency and cures rub-up problems. It is multifunctional and compatible with a wide range of waterborne as well as of solventborne paint systems. It is strongly adsorbed onto inorganic pigments and extenders, thus creating a dense charged layer, which contributes to electrostatic stabilization 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 are being optimized, using PAT-ADD DA 301. Improves the adhesion of paints and inks if applied onto polar substrates. The optimal amount of PAT-ADD DA 301 to be used is system related, but generally is between 0.1 and 0.5% calculated on the total weight of paint formulation, in case of post addition typically higher levels are needed, such as approx 1% PAT-ADD DA 301 on total weight of paint. For use as wetting agent in colorants/ tinters (typically in conjunction with PAT-ADD DA 601) higher dosages are required, generally 2 to 5% on total weight of the colorant or tinter. It is a REACH compliant.
