Process for preparation powder coating formulations by pressure release of a composition comprising a low molecular mass inert compound, with release of the low molecular mass inert compound, in which process one or more base resins and one or more hardeners for the base resins, or one or more self-curing base resins, and, if desired, further customary coatings components, are converted together or separately into a flowable form by heating, the low molecular mass inert compound is dissolved under pressure at least in one of the base resin or hardener components employed, either before these components are combined with the other components or in the already prepared mixture, the overall mixture is homogenized, and then the mixture of all components is released from pressure, with cooling.
