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 &#x3bc;m and 100 &#x3bc;m 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.

Multimaterial powder with composite grains for additive synthesis

Some embodiments are directed to the manufacture of functional composites (electrical conductors, thermal conductors, etc.) produced from coated powders.

Conductive composite produced from coated powders

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&#xb0; C. A binder composition of this kind has a polymerization starting temperature of 80&#xb0; C. and a gel time of between 35 s and 140 s at 180&#xb0; 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.
