Inks, lacquers and paints, varnishes can be challenging formulations because often they are required to have particularly long storage stability. High particle concentrations can be challenging for optical technologies - not so for LUM instruments. Stability testing in real-time and under accelerated conditions is always performed for the product in its original concentration. Measuring parameters and a large variety of accessories in combination with the combined optical and X-ray STEP technology allow the user for the necessary high flexibility to measure samples of lower (like aqueous based inks) and higher viscosity (like pigment pastes) undiluted. From optical point of view, from transparent up to completely turbid samples are measured. For details on the particle size distribution and further pigment particle characterization kindly see pigments. For coated pigment particles and coatings on surfaces, like cured paints on surfaces, kindly see Coatings & Surfaces. The additional CAT-technology is used for the determination of coatings strengths, saving time and money.
