Margret Böck Managing Director Microtrac Europe GmbH Meerbusch, Germany Modern coatings contain many components each having a specific purpose in maintaining colour, intensity, dispersion, viscosity, as well as acting as a milling aide. On the part of size consideration these substances have macromolecular and particle components all contributing to a measurement signal. Maromolecules are in the size range from sub-nanometer (nm) to 10 nm, whereas the scope of solid particles is between 1 nm and many micrometers (µm). Therefore, size analysis on coating materials requires skills to ...
