Abstract: Some embodiments are directed to a multimaterial powder used in the field of metallurgy and plasturgy. The multimaterial powder includes support particles having a median particle size distribution between 1 μm and 100 μm and functionalising particles having a median particle size distribution that is a factor of 10 to 1000 lower relative to the support particles. The powder is characterised in that the support particles and the functionalising particles form composite grains having a core-shell structure that each have a core formed by a support particle, and a shell, that covers between 10 and 100% of the surface of the support particle and which is formed by at least one surface layer of the functionalising particles.

Abstract: Some embodiments relate to a powder paint thermosetting binder composition that is solvent-free and includes at least one hardener and one cross-linking catalyst, and a first epoxy resin or a functionalized resin having at least one epoxy group. The resin has an epoxy equivalent weight of between 250 and 800 g/eq and a glass transition temperature of between 35 and 80° C. A binder composition of this kind has a polymerization starting temperature of 80° C. and a gel time of between 35 s and 140 s at 180° C. Some embodiments also relate to a paint composition containing a thermosetting binder composition of this kind, at least one pigment and, optionally, in addition a leveling agent and inorganic or organic fillers.
