  • Patent number: 10329375
    Abstract: A coating or plastics formulation contains a reaction product of at least one alkoxysilane-containing isocyanurate of the formula (I) with at least one hydrophilizing agent of the formula BOH which has at least one OH group, wherein R1, R2 and R3 in each case independently of one another are a linear or branched and/or cyclic C1-C8 alkylene radical, R?, R? and R?? in each case independently of one another are a linear or branched and/or cyclic C1-C8 alkyl radical, and B is a hydrophilic radical.

  • Patent number: 10093765
    Abstract: The present invention relates to alkoxysilane-functionalized allophanates, to methods for production thereof, and to the use thereof. In particular, the alkoxysilane-functionalized allophanate includes the reaction product of A) at least one alkoxysilane group-containing monourethane A) of the formula 1 Rn(OR1)3-nSi—R2—NH—(C?O)—OR3??formula 1, where R, R1, R2 and R3 are each independently hydrocarbyl radicals having 1-8 carbon atoms, which may be linear, branched or cyclic, or else may be integrated together to form a cyclic system, and n is 0-2, and B) at least one diisocyanate B), in a molar ratio of A) to B) of 3:1 to 1.5:1.

  • Publication number: 20150329751
    Abstract: A reactive composition contains A) an aqueous polyurethane-polyurea dispersion containing an uretdione group and having an internal emulsifier, the emulsifier having at least one ionogenic group which, in the case of an acidic ionogenic group, has a pKa in water of >8 at room temperature or, in the case of a basic ionogenic group, has a pKb of >8 at room temperature, B) at least one diamine and/or polyamine, wherein a ratio of a latent NCO group in the polyurethane-polyurea dispersion A) containing an uretdione group to the amine groups in component B) is from 4:1 to 1:1, and C) optionally, at least one member selected from the group consisting of an auxiliary, an adjuvant and a catalyst.
