Organic Pigments




Organic pigments are substances which consist of solid particles and are insoluble in the application medium, as described in the definitions of standard DIN EN 55943. Thus they are differentiated from dyestuffs which also consist of solid particles but are soluble in the end application medium.
The production of organic pigments takes place in industrial-scale plants, where all aspects of occupational health and safety and environmental protection are reliably met. 
All pigments which are used in paints and coatings systems have various particle sizes and specific surfaces due to their chemical structure and in order to achieve the desired optical and application properties. This means that different dispersant types and various amounts are needed in order to guarantee a complete covering of the pigment surface with the dispersing agent.  
The outlook for the pigments business appears strong in the light of the improving growth prospects for the paints and inks industry in the domestic as well as the global context.
