Abstract
A coated pigment that includes polymer encapsulations which act as a pigment dispersant and film forming agent, coating systems that include the coated pigment and methods for producing the coated pigment and the coating system are described. The polymer encapsulations of the coated pigments allow the coated pigments that are included in the coating system to be dispersed without the addition of any other dispersants and/or resins. Thus, the disclosed coated pigments simplify the process of making coating systems. The disclosed coated pigments also extend the shelf-life of the coating systems, and provide a final coating with enhanced pigment orientation and aesthetics.
Claims17
A coating system, comprising:
- a plurality of coated pigments;
- and
- a liquid carrier, wherein the plurality of coated pigments are dispersed in the liquid carrier,
- wherein each of the coated pigments includes
- a pigment having a surface, and
- a coating surrounding the pigment, the coating including polymer chains, the polymer chains surrounding the surface of the pigment and being attached to the surface of the pigment, and
- wherein the polymer chains of the plurality of the coated pigments are present in an amount sufficient to form a film that adheres to a substrate such that the coated pigments are physically or chemically bonded to the substrate when the coating system is applied onto the substrate and the liquid carrier is removed by evaporation, and
- wherein the coating system does not include any additional dispersants and resins other than those that are attached to the surface of the pigments.
