  • Patent number: 7261926
    Abstract: A solventborne coating material curable physically, thermally, or thermally and with actinic radiation, comprising A) at least one binder curable physically, thermally, or thermally and with actinic radiation, B) at least one color and/or effect pigment, and C) at least one colorless, transparent or opaque powder which is substantially inert with respect to the other constituents of the coating material and whose particles have an average size of from 1.0 to 10.0 ?m and a density of from 1.25 to 3.6 g cm?3 and its use as basecoat material for producing multicoat color and/or effect paint systems.

  • Patent number: 6930161
    Abstract: A self-crosslinking, branched polyurethane preparable by reacting (A) at least one hydroxyl-terminated polyester with a number-average molecular weight of from 500 to 4000 daltons, containing based on the polyester (A) (a1) from 60 to 95% by weight of structural units derived from aliphatic starting products and (a2) from 5 to 40% by weight of structural units derived from aromatic starting products with (B) at least one partially blocked polyisocyanate containing on average per molecule more than 1.5 and less than 3 free isocyanate groups, the equivalents ratio of free isocyanate groups in the polyisocyanate (B) to hydroxyl groups in the polyester (A) being >1, to give an isocyanato-terminated polyurethane prepolymer which is chain-extended and/or blocked with (C) at least one compound containing on average per molecule at least two isocyanate-reactive functional groups; process for its preparation, and its use as a binder in coating materials, adhesives, and sealing compounds.

  • Patent number: 6797771
    Abstract: The invention concerns a novel aqueous composition that can be hardened physically, thermally and/or with actinic radiation, containing a compound of general formula (I): X[NH—C(═O)—NH—Y—NH—C(═O)—OR]2 having at least one urea and urethane group, wherein the variables have the following meaning: R represents identical or different polyalkylene glycol ether radicals; X represents a bivalent substituted or unsubstituted arylene radical; Y represents identical bivalent substituted or unsubstituted arylene radicals, which are the same as or different from radical X or different bivalent substituted or unsubstituted arylene radicals of which none or one is identical to radical X. The invention also concerns the utilization of said compound for the production of novel aqueous coating materials, adhesives and sealants that can be hardened physically, thermally or thermally and with actinic radiation and their derivatives.
