Abstract: Aqueous polyurethane dispersions for production of strippable protective coatings are based largely on polyether-diols, optionally other diols, and monomers with isocyanate or NCO-reactive groups plus hydrophilic groups. The use of aqueous polyurethane dispersions (I) for the production of coatings suitable for use as strippable protective coatings, in which the polyurethane is based on: (a) di-isocyanates; (b) diols comprising (b1) 10-100 mol% diols with a mol. wt. of 500-5000, 70 mol% of which consists of polyether-diols and (b2) 0-90 mol% diols with a mol. wt. of 60-500; (c) other monomers with isocyanate group(s) or NCO-reactive group(s) plus hydrophilic or potentially hydrophilic groups to ensure water-dispersibility of the polyurethane; (d) optionally multi-valent compounds other than (a-c) with reactive alcoholic hydroxy, prim. or sec. amino or isocyanate groups; and (e) optionally monovalent compounds other than (a-d) with reactive groups as in (d). An independent claim is also included for strippable protective coatings obtained from (I).

Abstract: The use of an aqueous polymer dispersion containing at least one hydrogenated styrene/butadiene copolymer as a coating adhesive for adhesive bonding of flat substrates. An Independent claim is included for adhesive bonding of flat substrates involving: (i) coating of a first flat substrate with an aqueous polymer dispersion; (ii) drying of the coating; (iii) heating of the coating to a temperature higher than the coating activation temperature; and (iv) combining a second flat substrate with the first coated substrate to form an adhesive bond at a temperature higher than the coating activation temperature.

Abstract: The invention relates to a method for producing skins from polyurethane dispersions, comprising the following steps: 1) two-dimensionally coating the surface of a substrate or the surface of a film covering the substrate by simultaneously spraying an aqueous dispersion containing a polyurethane (polyurethane A) with ionic groups and an ionic or potentially ionic precipitating agent (precipitating agent F) in liquid form onto the surface of the substrate or the surface of the film covering the substrate, so that a covering is formed; and 2) removing the covering, or if the surface of the substrate was covered by a film, the composite structure consisting of the covering and the film, from the substrate.
