The purpose of a study was to evaluate the feasibility of using highly filled powders with 100 parts per weight of calcium carbonate and 10 parts per weight of polymer, acting as binder, as electrostatically applied paper coatings.
A long period of innovation in powder coatings came to a halt at the turn of the century, primarily due to economic and market changes. Promising new market areas now require developments in formulation or application. These include the use of plastic substrates and large objects which cannot be cured in ovens. Several ‘smart’ technologies have now been implemented as powder coatings.
