    Abstract: An apparatus and method for testing the surface quality of a coated 5 or uncoated substrate 7, in which fibres 3 of a brush 1 are pressed with a predetermined force e.g. by a spring 9 against the substrate and the brush rotates 15 about a rotation shaft 11 arranged perpendicularly to the substrate surface. At the same time is the brush is moved parallel to the substrate surface for a predetermined duration following which it is established, e.g. by determining gloss reduction or weight of material removed, whether a surface inhomogeniety exists that can be attributed to deformation or abrasion. The brush may be driven by a motor 13 moved along a rail 17. The pressing force may increase with longitudinal movement to provide a damage gradient. The brush may be plate shaped and mounted centrally or eccentrically on the shaft. The bristles may be of synthetic material e.g. metal wire or plastics such as PE, PP or PVC.

    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 method for the production of water-emulsifiable polyisocyanate preparations by (A) reacting di-isocyanates with polyether-alcohols to form products (E) with dispersant properties and then (B) mixing (E) with aliphatic polyisocyanates, involves forming allophanate groups by carrying out stage (B) in presence of an allophanatisation catalyst. A two-stage method for the production of water-emulsifiable polyisocyanate preparations (I) involves (A) making a reaction product (E) with dispersant properties from di-isocyanate(s) selected from tetramethylene-, hexamethylene- or dodecamethylene-di-isocyanate, 1,4-di-isocyanatocyclohexane, 4,4-di-(isocyanatocyclohexyl)-methane, trimethylhexanedi-isocyanate, tetramethylhexanedi-isocyanate, isophoronedi-isocyanate, 2,4- or 2,6-toluenedi-isocyanate, tetramethylxylylenedi-isocyanate, p-xylylenedi-isocyanate and/or 2,4- or 4,4-di-isocyanatodiphenylmethane together with mono- or poly-hydric poly(2-4C alkylene-ether-alcohols) and then (B) mixing (E) with aliphatic polyisocyanate(s) with an average NCO functionality of 2.5-3.5. Stage (B) is carried out in presence of an allophanatisation catalyst under suitable conditions for the formation of allophanate groups between (E) and the polyisocyanate. An independent claim is also included for water-emulsifiable polyisocyanate preparations (I) obtained by this method.
