Abstract: The invention relates to a method for surface-coating apparatuses and parts of apparatuses for the construction of chemical installations, for example apparatus, container and reactor walls, discharging devices, fittings, pumps , filters, compressors, centrifuges, columns, heat exchangers, dryers, reducin g machines, built-in parts, packing and mixing mechanisms. The method is characterised in that bumps with an average height of 100 nm to 50 .mu.m are produced on the surface to be coated, at average intervals of 100 nm to 100 .mu.m, before the surface is coated by currentlessly depositing a layer of metal or a layer of a metal-polymer-dispersion using a galvanisation bath containing a metal electrolyte, a reduction agent and optionally, a polymer or polymer mixture to be deposited, in dispersed form.

Abstract: The invention relates to a method for coating a reactor. Said method is characterised in that a metal layer or a metal polymer dispersion layer is deposited on the inner surface of the reactor in a currentless manner by contacting the surfaces to a metal electrolytic solution which contains a reduction means and a halogenated polymer in dispersed form in addition to t he metal electrolyte. Said halogenated polymer can optionally be deposited.

Abstract: A solid pigment preparation contains by wt. (a) a pigment (60-95%); (b) a water-soluble anionic surfactant (5-40%) which is a polymer of an ethylenically unsaturated mono- and/or di-carboxylic acid optionally copolymerized with an acid function-free vinyl monomer, the alkoxylation product of such a (co)polymer or a salt of the (co)polymer or its alkoxylation product; and (c) a polyether-based nonionic surfactant (0-20%). An Independent claim is also included for production of the pigment preparation by wet comminuting pigment (A) in a suspension containing at least a part of (B) and optionally also component (C) and then optionally adding any remainder of (B) and/or (C) and drying the mixture.
