    摘要: The present invention relates to a composite material comprising, by weight, the total being 100% : A) 40 to 90% of PVDF homopolymer or copolymer crystallized essentially in the &bgr; form, B) 10 to 60% of a conductive filler, C) 0 to 40% of a crystalline or semi-crystalline polymer, D) 0 to 40% of a filler other than C, such that the crystals in the &bgr; form are nucleated on the surface of the particles of the conductive filler. This material is conductive with a resistance which is self-regulated by the temperature. It shows an increase in the resistance as a function of the temperature (PTC or “Positive Temperature Coefficient” effect), so that the intensity stabilizes at an equilibrium temperature.

    摘要: The present invention concerns the field of fluorinated hydrocarbons and relates to novel compositions containing fluorinated hydrocarbons and oxygenated solvents. More particularly, the compositions comprise a fluorinated base, diacetone alcohol (DAA), and DMSO and/or secondary butanol. These novel compositions can be used in particular in all solvent applications of HCFC 141b (hydrochlorofluorocarbon 141b), in particular in various operations for treating solid surfaces, such as the cleaning, degreasing, defluxing or drying of solid surfaces.

    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.
