According to the definitions in DIN 55943, ISO 4617 and 4618, and ASTM D16-84, the term colorants is applied to pigments, dyes, and extenders. These are mixed with binders, resins, and plasticizers to produce the desired visual and functional effects (e.g., corrosion protection) as a surface coating.
Depending on the challenges posed by the surface characteristics of the substrate, the composition of coating systems has to be meticulously monitored. To characterize your colorants, we offer you a variety of analytical techniques, from ion chromatography, titration, and voltammetry to spectroscopy.
