Special Features and Benefits - BYK-156 stabilizes the pigments and fillers by electrostatic repulsion and is recommended for aqueous emulsion paints. The additive increases gloss, lowers viscosity and improves storage stability. BYK-156 does not have a foam stabilizing effect. As an ammonium salt it affects curing and water resistance to a lesser extent than metal salts.

Recommended Levels -  Amount of additive (as supplied) based upon pigment:

  • Inorganic pigments: 1.5-8 %
  • Titanium dioxides: 1-2 %
  • Fillers: 0.4-0.8 %

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing -  Instructions For optimum performance, the additive must be incorporated into the mill base before the addition of pigments.
