    Abstract: The invention relates to a two-step method for the production of a water-emulsifiable polyisocyanate preparation. In the first step (A), a dispersingly active reaction product is made from at least one diisocyanate and at least one polyalkene ether alcohol and in a second step (B) the reaction product is mixed with an aliphatic polyisocyanate in the presence of an allophanation catalyst. The invention also relates to a water-emulsifiable polyisocyanate preparation which can be obtained according to said method in addition to the use of said preparation in aqueous coating agents and in adhesive dispersions.

    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.
