Chemical Name: Pigment
A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food, and other materials.

1- Providing color (shades)
2- Improve the strength and resistance of the paint layer, especially anticorrosive inorganic pigments
3- Improve film durability and resistance in poor weather conditions
4- Improve other properties of film
The following are some of the properties of pigments especially in manufacturing process and applications:
1) Tinting strength
3) Heat stability
6) Opacity or transparency
7) Resistance to alkalis and acids
8) Reactions and interactions between pigments
9) Creating chemical and physical resistance.
Types of pigments:
Pigments could be classified in two ways:
1. Natural or Synthetic (Artificial made)
2. Organic or Inorganic
The majority of inorganic pigments are brighter and last longer than organic ones. Organic pigments made from natural sources and different chemical reaction, but most pigments used today are either inorganic or synthetic organic ones. Synthetic organic pigments are derived from coal tars, other organic reaction which most of them is based on metal organic component and other petrochemicals. Inorganic pigments are made by relatively simple chemical reactions notably oxidation or are found naturally as earths.
Limitations of Natural Pigments:
1. Natural pigments are produced by traditional methods.
2. These pigments have lower intensity in comparison to Synthetic pigments.
3. These pigments are not efficient for coloring of the synthetic clothes.
4. The natural pigment has an impurity in the form of silica, which is very costly to remove, while the synthetic pigment is relatively pure.
5. The liquid waste of natural pigments contains heavy metals which is much more than the desired limit

Usages & Maintenance:
Prevent formation of dust. Take precautionary measure against electrostatic charges- Earthing is necessary during loading operation. Avoid exposure to open flame or spark. Avoid contact with eyes and skin.
1. A moderately dry, well-ventilated area is considered to be adequate for handling and storage.
2- Protect from extreme heat and cold. Keep away from sources of ignition. Avoid dust formation.
