Pigments for Paints, Coatings and Inks

Pigments are important constituents in paints, coatings and inks. They are added to paints and coatings formulations to impart color, bulk or a desired physical and chemical property to the wet or dry film.

This selection guide will help you understand more about use of pigments, differences between pigments and dyes, types & different families of pigments, their properties & performances, pigment dispersions, applications in the paints & coatings industry and much more.

What are Pigments?


Pigments for Paints, Coatings and Inks Pigments are finely ground natural or synthetic, insoluble particles used to impart color when added to paints and coatings formulations. They are also used to impart bulk or a desired physical and chemical property to the wet or dry film. Some of the main pigment classes include:

  • Organic pigments
  • Inorganic pigments
  • Functional pigments
  • Special effect pigments 

While organic pigments do not disperse easily and form agglomerates (clumps of pigment particles), inorganic pigments get more easily dispersed in the resin. Functional fillers impart a desired property to the coating like corrosion inhibition and special effect pigments create optical effects like metallic, hammer finish and diverse color perceptions depending on the angle.
