  • Patent number: 5989715
    Abstract: The present invention relates to a layer product consisting of thermoplastic polyurethane which is stabilized against ultraviolet radiation and is based on diisocyanates, diols as chain extenders, polytetrahydrofuran or linear polyesterdiols.
    Type: Grant
    Filed: January 20, 1998
    Date of Patent: November 23, 1999
    Assignee: BASF Coatings AG
    Inventors: Leonidas Kiriazis, Frank Prissok, Karl-Heinz Dickerhof
  • Patent number: 5223323
    Abstract: The present invention relates to a process for coating finish foils and endless edges, wherein an acid-curing aqueous coating composition, on the basis of aminoplast resin/compound containing hydroxyl groups/self-crosslinking acrylate dispersion, is applied and baked in. The coating composition used contains 5 to 20% by weight of one or more fillers of a mean particle size from 0.015 to 10 .mu.m, a maximum particle size of .ltoreq.40 .mu.m and a density of .ltoreq.2.9 g/cm.sup.3.The invention also relates to the coating compositions positions used in the process and to finish foils and endless edges produced by the process, which especially have the advantage of an extremely low formaldehyde emission, particularly as a composite with a low-formaldehyde chipboard.

  • Patent number: 4942198
    Abstract: The invention relates to aqueous two-component lacquers containing pigments and other customary additives for single-layered coating of finish film and continuous edges. The two-component lacquers according to the invention are such lacquers in which the first component (component (A)) contains 0.1 to 15% by weight, preferably 2 to 10% by weight, based on the total weight of component (A), of a blocked acid as a potential hardening catalyst and 10 to 90% by weight, preferably 20 to 65% by weight, based on the total weight of component (A), of an aqueous dispersion of a self-crosslinking polyacrylate, in which the polyacrylate contains, as the groups which facilitate self-crosslinking, acid amide derivative groups which correspond to the general structural formula --CO--N(R.sup.1)--CH(R.sup.2)--OR.sup.3, in which R.sup.1 =an H atom or a --CH(R.sup.2)--OR.sup.3 grouping, R.sup.2 =an H atom or a --COOR.sup.4 group, R.sup.
    Type: Grant

  • Patent number: 4940841
    Abstract: The invention relates to aqueous two-component paints containing customary additives and, if appropriate, pigments, for one-coat coating of finishing sheeting and continuous edging, characterized in that the paints containing as paint component (I)(A) 40 to 85% by weight, preferably 60 to 85% by weight, of an aqueous dispersion of a self-crosslinking polyacrylate resin, which contains as the groups capable of bringing about the self-crosslinking acid amide derivative groups corresponding to the general structural formula--CO--N(R.sup.1)--CH(R.sup.2)--OR.sup.3,whereinR.sup.1 =a hydrogen atom or a --CH(R.sup.2)--OR.sup.3 group,R.sup.2 =a hydrogen atom or a --COOR.sup.4 group,R.sup.3 =a hydrogen atom or a hydrocarbon radical of 1 to 10 carbon atoms, preferably the methyl, ethyl, (iso)propyl or (iso)butyl radical,R.sup.
