UNIQ®SPERSE 680 U is a wetting and dispersing additive for water-, solvent- and solvent free based applications. The dispersant is especially developed for grinding organic pigments, but gives also excellent performances and jetness for HCC carbon black. The dispersant is also suited for inorganic pigments and the dispersant can be used for the preparation of resin free pigment concentrates.
