Description
Efka FA 4608 is a low-molecular-weight wetting and dispersing additive for inorganic pigments (especially titanium dioxide) and extenders, delivering reduced dispersing time, increased gloss, and reduced flooding of pigments. In white bases, it improves the color acceptance of tinting pastes, resulting in higher pigment efficiency, and also reduces flooding and floating in those bases. For a higher-performance, acidic-group version suited to a broader range of coating systems, see also Efka FA 4611, and for iron oxide dispersion specifically, see Efka FA 4609. For organic pigments and organically treated bentonite gels, see Efka FA 4644 — all related BASF Efka dispersing agents from the same Additives Team.
