functional pigment

Functional pigments are specialized materials that provide unique chemical properties to coatings beyond just color. These pigments are insoluble, finely ground particles used to impart specific functions. Examples include zinc oxide for mildew control, zinc chromate for corrosion inhibition in primers, and antimony oxide for fire retardancy. Magnetic pigments, like iron oxide, are used in data storage.1

Pigments, in general, are insoluble particles that provide color, opacity, and control over gloss and flow. They can be organic or inorganic, with inorganic pigments often being brighter and more durable. While organic pigments are synthesized from hydrocarbons, inorganic pigments are produced through chemical reactions or found naturally. The color of a pigment arises from its selective absorption of light wavelengths.23
