Coating Colour Kitchens / Coating Colour Preparation

As system supplier for coating colour processing systems, GAW has decades of experience and worldwide references in planning, delivery, installation and commissioning of complete coating colour kitchens.
The coating colours are prepared in the coating colour kitchen where individual components are measured out into a special mixing unit based on the present recipe, according to quantity and sequence, and then mixed intensively.


The composition of the coating colour depends on the demands for paper quality. Various raw and auxiliary materials are used depending on the desired properties such as pick resistance and wet strength, uniform colour tone, absorbency, opacity, white level, smoothness and gloss:

  • Pigments (primarily kaolin, calcium carbonate or talcum)
  • Natural binding agents (casein or starch) and/or synthetic binding agents
    (synthetic dispersion binders)
  • Auxiliary materials (optical brightener, thickening agent, dispersing agent, etc.)

Homogenous mixing of the components is an important requirement for the processing stage of the coating. The coating colours are prepared in a fully automatic process controlled by computers. Measurement systems such as the GAW Quality Loop, continuously monitor the adherence to important quality parameters.
