Paint consist of these major component

1. Pigment – Its is the color shade

2. Binder – Which hold the pigment to the surface.(Adhesion or glue)

Inorganic Pigments- These are generally are metallic oxides or synthetics.It can be materials like lead oxide, cobalt blue, chromium oxide, cadmium yellow, molybdate orange, and nickel titanate.

Inorganic Pigments         Refractive Index

  • TiO2 (Anatase)———–2.55
  • Antimony Oxide———2.20
  • Zinc Oxide—————–2.01
  • Calcium Carbonate—— 1.65
  • Fumed Silica————–1.45

TiO2(rutile) is considered the best inorganic pigment, so when if the paint has a shade which comes from TiO2 pigment the price will go up. Thus price will be low if used fumed silica.

 

Organic pigments are usually found in nature and categorized into six types :

  • Acid and base dye Pigments
  • Diazo Pigments
