Colour measurement of solid and powdery chemical products

Powdered chemicals are used in numerous industries such as the coatings, food, building materials, pharmaceuticals, plastics, cosmetics and detergents industries, to name but a few. Yellowness (Yellowness Index YI), whiteness (Whiteness Index WI), colour fastness and also UV resistance, e.g. of pigments and fillers, flakes for paints, superabsorbents, granulates, resins and powder coatings are tested.

The world’s leading chemical manufacturers rely on HunterLab solutions to ensure the quality and consistency of finished products and raw materials throughout their supply chains with accurate and repeatable measurement results.

Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific colour measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colours authentically. HunterLabs Vista spectroph...
