Abstract
An effect pigment preparation comprises an effect pigment, a dispersive additive, and a passivating agent. The preparation is dry, the pigment comprises about 84% or more of the mass of the preparation, the dispersive additive comprises up to 15% of the mass of the preparation, and the number of theoretical layers of the passivating agent is from about 2 to about 12. The effect pigment preparation is non-dusting and can be easily stirred into aqueous, solvent, or UV curing-based liquid coatings formulations.
