Abstract (en)
[origin: EP0920921A2] The fluid is a chemically inert and electrically non-conducting material. The particles of at least two different solids, or the particles of at least one solid and a surface to be coated, have a different static charge. The fluid is a liquid or supercritical gas, e.g. liquid nitrogen or supercritical/liquid carbon dioxide, at a pressure of more than 1bar. The solid particles have an average diameter of 0,01 mu m to 50 mu m. After mixing, the gas is evaporated to create a dry product.
