    摘要: The invention concerns to the use of a powder comprising 99.95 to 95% of at least one polyamide and 0.05 to 5% of at least one silane for coating metals. This powder may be prepared by simple dry blending of the constituents. The silane can also be added to the molten polyamide in a mixing device and the resulting product reduced to powder. The addition of silane makes it possible to significantly improve electrostatic application by preventing a substantial portion of the powder from falling off during the electrostatic discharge which follows application, while providing lasting adhesion between the coating and metal. Advantageously, the silane is chosen from aminopropyltriethoxysilane and aminopropyltrimethoxysilane. The invention also concerns a method of coating an object with a film resulting from melting a thin layer of the powder.

    摘要: The present invention concerns a process for preparing a polymer nanocomposite composition, the process comprising: a) mixing a melted polyamide of inherent viscosity under 1 and a nanofiller to disperse the nanofiller in said polyamide; and b) subjecting the previous mixture to polymerization conditions to polymerize the polyamide and to form the polymer nanocomposite composition. Advantageously the inherent viscosity of the polyamide is under 0.9 and preferably between 0.4 and 0.8. Step a) is carried out in an extruder or a mixer. Advantageously a mono or twin-screw extruder is used. Step b) could be made either in melted state or in solid state. It is easier to make it in the same apparatus as step a). Should step a) is carried out in an extruder, step b) is made in the same extruder. Polymerization of step b) can be carried with a catalyst and/or by having the extruder zones in which step b) takes place to operate under vacuum.

    摘要: The present invention relates to the use of a powder for coating articles, this powder comprising, by volume, 99 to 65% of at least one thermoplastic polymer and 1 to 35% of beads of a material that retains its initial shape at the processing temperatures for obtaining the coating. This powder may be prepared by simply dry-blending the constituents. The invention also relates to this powder. The invention relates in particular to rough coatings obtained from powders, for a dishwasher basket, which contain solid or hollow glass or ceramic beads added by dry-blending them with the polyamide powder. Because of their roughness, these coatings improve the drying in dishwashers. The addition of glass beads furthermore improves the quality of the fluidization.
