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.
