Abstract

A process is disclosed for preparing an aqueous powder coating dispersion from a solid powder coating composition and an aqueous medium, said composition comprising 1) a homogeneous mixture of a resin, a cross-linker, and, optionally, a pigment, a catalyst, an initiator, and/or one or more additives, or 2) a radiation-curable resin and, optionally, a cross-linker, a pigment, a catalyst, an initiator, and/or one or more additives. The process is characterised in that it comprises the steps of: a) elevating the temperature of solid powder coating composition such that a molten-like substance is obtained the temperature of which is above the melting point or the glass transition temperature (Tg) of the solid powder coating composition, b) optionally cooling down the molten-like substance, c) dispersion said substance, in the cooled down state or not, in the aqueous medium.
