Résumé : |
The authors discusses the dispersion of Complex Inorganic Colour Pigments (CICPs) in powder coatings.
The previous article discussed the general properties of the class of high-performance pigments known as Complex Inorganic Colour Pigments (CICPs). These pigments are known for their outstanding inertness and resistance to chemicals, migration and weathering. They also have some inherent colouring properties advantageous for powder coatings. The control of colour in powder coatings depends on the predictability of the dispersion of the coloured pigments. CICPs have dispersion properties that produce colour that is controllable and stable. CICPs give controllable colour because the relatively higher use-rates as compared to organic pigments allow more advantageous mixing ratios. This can be demonstrated in the tinting of near white colours. Stability is beneficial if the powder coating needs to be re-extruded to correct for other colourants performance. The CICPs will not develop as much colour as standard organic pigments. Stability can be demonstrated by comparing a light blue tint colour made with either standard phthalo blue (PBI15.1), or Cobalt Blue (PBI28). |
