  • Patent number: 7129280
    Abstract: Mixtures curable thermally and with actinic radiation and containing carbamate and/or allophanate groups, comprising (A) at least one of (A1) low molecular mass compounds, oligomers and polymers containing allophanate groups, carbamate groups, and carbamate and allophanate groups, and (A2) low molecular mass compounds, oligomers and polymers containing allophanate groups, carbamate groups, and carbamate and allophanate groups, and additionally allophanate- and/or carbamate-reactive functional groups, ?which are substantially or entirely free from reactive functional groups which contain at least one bond which can be activated with actinic radiation, and (C) at least one constituent containing on average per molecule at least one reactive functional group having at least one bond which can be activated with actinic radiation; with the proviso that if only (A1) is used, the mixtures further comprise (B) at least one of low molecular mass compounds, oligomers and polymers containing allophanate- and/or c

  • Publication number: 20060173120
    Abstract: Coating materials including at least one hydroxyl-containing (meth)acrylate (co)polymer, at least one carbamate- and hydroxyl-containing compound and at least one amino resin, where at least 10 equivalent % of the hydroxyl groups present in the (meth)acrylate (co)polymers and/or the carbamate and hydroxyl containing compound are primary hydroxyl groups. The coating materials after curing have a storage modulus E? in the rubber-elastic range of at least 1.5*107 Pa, the storage modulus E? having been measured by dynamic mechanical thermoanalysis (DMTA) on homogeneous free films with a thickness of 40±10 ?m. Also included is a processes for preparing the coating materials and applications therefor.

  • Publication number: 20060116488
    Abstract: A multicomponent system comprising (I) a component comprising (A) an oligomer and/or polymer containing allophanate groups and/or carbamate groups, (B) an oligomer and/or polymer containing isocyanate-reactive functional groups, (C) a partly or fully alkylated amino resin, and (D) a compound containing groups which can be activated with actinic radiation; and (II) a component comprising (E) a polyisocyanate, with the proviso that the equivalents ratio of isocyanate groups in component (II) to isocyanate-reactive functional groups in component (I) is from 0.2:1 to 1:0.2 and the equivalents ratio of allophanate groups and/or carbamate groups in the oligomer and/or polymer (A) to the N-methylol ether groups or the N-methylol and N-methylol ether groups in the amino resin (C) is from 0.2:1 to 1:0.2; and its use to produce mixtures curable thermally and with actinic radiation.

  • Publication number: 20050119422
    Abstract: Heat-curable thixotropic mixtures containing carbamate and/or allophanate groups, comprising (A) at least one oligomer and/or polymer selected from the group consisting of oligomers and polymers containing allophanate groups, carbamate groups, and carbamate and allophanate groups, and (B) at least one thixotropic agent selected from the group consisting of urea or urea derivatives preparable by reacting at least one amine and/or water with at least one polyisocyanate, with the proviso that the mixture in question, based on its solids, further comprises at least one silica as thixotropic agent (C), and contains the thixotropic agent (B) in an amount of from 0.1 to 5% by weight if the oligomers and polymers (A) contain no allophanate groups; processes for preparing the mixtures, and their use as coating materials, adhesives and sealing compounds.
