Pigments are divided into two categories, mineral and organic. Mineral pigment is one of the oldest types of those that is obtained from different parts of the earth’s crust and is broken, crushed and washed and classified according to the particle size.
In addition to the earth’s crust, we also get pigments from various plants and animals. Mineral pigments later formed new colors by mixing with each other, and gradually the artificial type of those became popular, which is usually produced through chemical processes.
But the second type of those, the organic pigment, is not found naturally and is those synthesized . The newest pigments have a metallic organic structure. One of the most important organic pigments is the phthalocyanine group, which includes a range of blue and green colors. For example, copper phthalocyanine is a blue pigment that is a valuable pigment due to its good resistance to various factors.
Pigments are solid particles whose addition to color not only makes them coated and colored, but also certain properties such as surface protection against weathering and corrosion and axial properties such as layer strengthening, proper hardness, flamm ability and Gives other properties to the desired surface.
Although the emergence of new pigments has been slow over time, they are now widely used, and the largest manufacturers of those in the world include the United States, China, Germany, Japan and India.
