Abstract: Described herein is a composite material including perfluoroalkoxy polymer powder, carbon black powder and a film-forming liquid, where the proportion by mass of the film-forming liquid is from 0.05% by weight to 1.0% by weight, the film-forming liquid at least partially wets the surfaces of the particles of the perfluoroalkoxy polymer powder, and the particles of the carbon black powder adhere to the film-forming liquid and/or the particles of the perfluoroalkoxy polymer powder. Also described herein are a production process for coating metallic surfaces, which uses the composite material as starting material, and further uses of the composite material.

Abstract: The surfaces of apparatuses and apparatus parts for chemical plant construction, including, for example, apparatus, container and reactor walls, discharge apparatuses, fittings, pumps, filters, compressors, centrifuges, columns, heat exchangers, dryers, comminuting machines, internals, packings and mixing elements, are coated by a process wherein protuberances having a mean height of from 100 nm to 50 &mgr;m with a mean spacing of from 100 nm to 100 &mgr;m are produced on the surface to be coated and the coating is applied thereon by currentless deposition of a metal layer or of a metal-polymer dispersion layer with the aid of a plating bath which contains a metal electrolyte, a reducing agent and optionally a polymer or polymer blend to be deposited, in dispersed form.

Abstract: The invention relates to an apparatus and a process for producing foam moldings by sintering prefoamed polymer particles by means of superheated steam in a mold which has been arranged in a steam chamber into which the superheated steam is introduced and from there forces its way though nozzles into the mold. The inner walls of the steam chamber have been coated with a cured epoxy resin.

Abstract: The invention relates to a process for the production of a heat transfer device, which comprises electroless chemical deposition of a metal/polymer dispersion layer, in which the polymer is halogenated, on a heat transfer surface. The invention furthermore relates to a process for the production of a heat transfer device, wherein a metal/phosphorus layer with a thickness of from 1 to 15 &mgr;m is applied by electroless chemical deposition before application of the metal/polymer dispersion layer. The invention furthermore relates to a heat transfer device which can be produced by a process according to the invention, and to the use of a coating, produced by electroless chemical deposition of a metal/polymer dispersion layer, in which the polymer is halogenated, for reducing the tendency of the coated surfaces to accumulate solids from fluids, causing fouling.
