EFKA-4046 is a polymeric dispersant for stabilizing inorganic and organic
pigments. This results in:
improved gloss
reduced flooding problems
higher colour strength
lower viscosity
Application: EFKA-4046 is used for all kinds of solvent-based coatings as well as
pigment concentrates. (see our concept for resin minimal pigment
concentrates based on EFKA polymeric dispersants)
Addition: Calculation method for the required amount of active ingredient on
pigment:
Inorganic pigments : 10% of oil absorption value
Organic pigments : 25 - 50% of BET- value
Carbon blacks : 20% of DBP absorption value
Incorporation: EFKA-4046 should be incorporated in the mill base before adding the
pigments.
High molecular weight polymeric dispersant for deflocculation of pigments. Can be used for stabilizing inorganic and organic pigments. Improves gloss. Reduces flooding problems. Provides high colour strength and low viscosity. Suitable for all kinds of solvent-based coatings as well as
pigment concentrates. (Suitable for resin minimal pigment concentrates)
Should be incorporated in the mill base before adding the pigments.
