Abstract (en)
[origin: WO2022074350A2] The invention relates mainly to a pigmented pulverulent composition based on polyamide for coating substrates, comprising: (a) 40% to 99% by weight of at least one polyamide; (b) 1% to 30% by weight of at least one pigment; and (c) 0 to 30% by weight of at least one additive, in which the polyamide has an inherent viscosity, as measured using a Ubbelohde tube at 20°C on a solution at 0.5% by weight in m-cresol according to standard ISO 307, except that the measurement temperature is 20°C instead of 25°C, of greater than 0.7 (g/100g)-1, and in which the composition has a volume median diameter Dv50, as measured according to standard ISO 9276 - parts 1 to 6, of from 10 to 200 μm, preferably 30 to 50 μm. It further relates to a method for producing said composition, to the use thereof for coating a metallic substrate, and to an object comprising a metallic substrate coated with a coating obtained with the pigmented pulverulent composition based on polyamide.
