Inorganic pigments are obtained from mixed metal oxides and are produced by a high temperature calcinations process. These pigments are not affected by strong acids, base and oxidizing agents. Also inorganic pigments are non-migratory, do not bleed and are non-warping. Most inorganic pigments can withstand various temperatures and bad climatic conditions; they are heat resistant, have resistance to other chemicals and are easy to disperse.
There are a variety of inorganic pigments available and are classified primarily from the source they are derived from. Some of the inorganic pigments include Chrome, which is derived from lead, Cadmiums, which are derived from cadmium compounds, and Irons that are derived from various iron oxides among others. Inorganic pigments are solid materials that obtain their transparency owing to their extremely small size and shape.
Inorganic color pigments are used in various industries, which include coil coatings, powder coatings, industrial coatings, architectural coatings among others. They are also used in the coloring of plastics, buildings, constructions etc… It finds its application even in the automotive segments as a colorant for engineering plastics.
Owing to the quality of industrial products, which have been improving over the past few years, the demands on their appearance and durability are increasing as well. Due to their fastness properties and their tolerance to adverse conditions, they are the most preferred pigments used in constructions. Inorganic pigments are the most stable class of pigments that have been manufactured as of today.
The key drivers for the inorganic pigment market include rapid growth in urbanization, the paints and the coatings market, the construction agency, the building material and plastic industry. The demand for inorganic pigments is expected to be the highest in developing countries. These inorganic pigments are mainly used in the automotive industry due to its durable properties.
The market for automotives in developing countries along with the plastic, paint and coatings industry is growing at a rapid pace especially in emerging economies like India and China and hence the demand for inorganic pigments is anticipated to be high in these countries.
The main setbacks of the inorganic pigment industry are coping with continuous globalization, markets that are mature in a few applications and regions and the excess production of commodity pigments. The adverse environmental effects inorganic pigments cause can be a restrain for its market especially in Europe. However due to the lack of stringent regulations in Asia Pacific countries especially in countries like India and China, inorganic pigments are used produced and used on a large scale.
The key segments for this market include North America, Europe, Asia Pacific and Rest of the world (RoW). The most widely used pigments are manufactured from iron oxide. The largest manufactures of inorganic pigments is China, followed by North America and finally Europe. Demand for inorganic pigments is seen to be declining in western countries while demand in Asian countries is increasing especially in China. The inorganic dye market is mature in Japan and is not likely to increase by a huge margin over the next few years. The consumption of inorganic pigments is expected to grow significantly in India and China in the near future.
The key companies profiled for pigments include:
- Ferro Corporation GmbH,
- Shepard Color Company,
- Bayer AG,
- Rockwood,
- Atlanta AG,
- Apollo Colors,
- Honeywell International
- Todo Kogyo.
