    Abstract: The method involves impregnating wood, wood material or a material for manufacturing a wood material with a hardenable aqueous composition, which contains at least one cross-linkable compound, selected from low-molecular weight compounds V, having at least two N-bonded groups of formula CH 2OH, where R = hydrogen or C1-C4 alkyl, or one 1,2-bishydroxyethan-1,2-diyl group, bridging two nitrogen atoms. The method then involves precondensates of the compound V and reaction products or mixtures of the compound V with at least one alcohol, selected from C1-C6 alkanols, C2-C6 polyols and oligoalkylene glycols. Then method involves treating the obtained material at an elevated temperature and, optionally, transforming said material into a wood material and treating at least one surface of the wood or wood material to be treated with a surface treatment agent and, optionally, drying the treated surface in a manner known per se. An independent claim is also included for the surface treatment.

    Abstract: A water dispersible, radiation curable polyurethane comprises organic aliphatic or alicyclic polyisocyanates, cycloaliphatic diols and/or cycloaliphatic diamines, compounds having at least one isocyanate reactive group and at least one radically polymerizable unsaturated group and compounds having at least one isocyanate reactive group and at least one dispersion aiding group. A water dispersible, radiation curable polyurethane (I) comprises: (A) organic aliphatic or alicyclic polyisocyanates; (B) cycloaliphatic diols and/or cycloaliphatic diamines; (C) compounds having at least one isocyanate reactive group and at least one radically polymerizable unsaturated group; (D) compounds having at least one isocyanate reactive group and at least one dispersion aiding group; (E) optionally compounds having at least two isocyanate reactive groups having a mol. wt. of less than 1000 g/mol; (F) optionally compounds having at least one isocyanate reactive group that are different to (A)-(D). Independent claims are included for: (i) a polyurethane dispersion (II) comprising the polyurethane (I) and optionally 0-10 wt.% of a photochemical and/or thermal initiator and 0-10 wt.% of a UV absorber and a HALS compound; (ii) a process for the coating of substrates by application of the polyurethane dispersion (II), optionally containing conventional paint additives, onto a substrate and curing by means of electron irradiation or UV light under oxygen, or preferably under inert gas; (iii) the resulting coated substrate.

    Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.
