BYK-Synergist 2100 is a pigment synergist for solvent-borne and solvent-free coating systems. It enhances the performance of polymeric wetting and dispersing additives, particularly in stabilizing pigments like phthalocyanine blue, phthalocyanine green, organic violet pigments, and carbon blacks. It provides good wetting properties and functions as a synergist to improve pigment dispersion. The product is in powder form and is used in both solventborne and solventless & high solids coatings.

Special Features and Benefits

The synergist enables high-molecular weight wetting and dispersing additives to be more efficiently adsorbed on the surface of phthalocyanine blue and phthalocyanine green, organic violet pigments and carbon blacks; thereby increasing the effectiveness of the wetting and dispersing additives. Stabilization of the pigments is improved and higher pigment contents are possible as a result of a reduction in the viscosity.

Recommended Use
The synergist is always used in combination with high-molecular weight wetting and dispersing additives and is recommended for coatings and pigment concentrates.

Recommended Levels
Additive dosage as supplied based on pigment:

  • Phthalocyanine pigments (PB 15, PG 7, PG 36): 3-5%
  • Organic violet pigments (e.g. PV 19, PV 23): 3-5%
  • Carbon blacks (PBk 7): 3-5%

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 powdered synergist must be incorporated in the millbase together with polymeric wetting and dispersing additives prior to adding the pigments.
