Ser-ad FX 504

Low foaming polymeric pigment dispersing agent that work effectively for many hydrophillic pigments and extenders, used in aqueous coatings, based on polymeric binders as PVAC, PAC, PSB, PSAC dispersions, terpolymers and latices. Applied as dispersing agent in many hydrophillic pigments and extenders in aqueous mediums such as titanium dioxides, calcium carbonate, barium sulphate, iron oxides. Is strongly adsorbed onto these pigments and extenders and reduces the viscosity of the milling paste. If strongly hydrophobic pigments are used such as most organic types, it is recommended to use it in combination with a wetting agent. Offers narrow distribution of molecular mass of the polymer, provides optimal effectivity, decreases flocculation, flooding, pigment settling, increases opacity. Reduces required amount of defoamer, no bubbles or craters. Insensitive to hydrolysis, provides longterm stability of the paint Added prior the dispersion stage. Recommended usage level: 0.1 - 1 % calculated on the total quantity of pigment and extender.
