Abstract
The present invention relates to a process for the production of a powder coating, in which a suspension of powder particles is sprayed and the spray jet is directed onto the substrate to be coated, characterized in that 1.) a suspension of powder particles in a liquefied gas is employed, the gas having been liquefied under a pressure of not more than 20 bar, and 2.) the liquid gas is vaporized before, during or after the spraying of the suspension.
Claims25
A process for the production of supported catalysts, comprising the steps of:
- a) suspending a catalyst active substance in a liquefied gas, producing a suspension, wherein the gas is liquefied at a pressure of not more than 20 bar, b) depositing the suspension into the pores of a catalyst support substance by spraying, and c) vaporizing the liquefied gas.
A powder coating suspension, comprising a suspension of powder particles in a gas, wherein the gas is liquefied at a pressure of not more than 20 bar.
