Powder-based dispersing agent for aqueous based pigments and fillers and powder blends. For carbon black, zinc oxides and dyes.

Recommended levels based on pigment level -

Inorganic Pigments: 1 - 5%


Incorporate the dispersing agents into the aqueous binder during high speed dispersion before the addition of the pigments. For higher than 30% pigment loadings this mill base must then be processed through high energy dispersion techniques such as beadmills, basket mills and three roller mills.
