  • Patent number: 10336856
    Abstract: An alkoxysilane-functionalized and allophanate-functionalized coating material including a) a binder component of 10-99 wt % of at least one reaction product of I. and II. wherein I includes A) at least one alkoxysilane-containing monourethane A) of the formula 1 Rn(OR1)3-nSi—R2—NH—(C?O)—OR3 wherein R, R1, R2 and R3 represent hydrocarbon radicals having 1-8 carbon atoms, and n represents 0-2, and B) at least one diisocyanate B), and II includes the subsequent reaction of C) with at least one diol and/or polyol C), in a ratio of NCO groups of reaction product I to OH groups of the diol and/or polyol II. C) of 1.0:1.5 to 1.0:0.6; b) 1-90 wt % of at least one further binder component distinct from a) a hydroxyl-containing or amino-containing binder component, c) 0-50 wt % of at least one polyisocyanate having an NCO functionality of at least 2, d) 0-5 wt % of at least one catalyst, wherein components a)-d) add up to 100 wt %.

  • Patent number: 10093826
    Abstract: The present invention relates to alkoxysilane-functionalized, allophanate-containing coating compositions, to a process for producing them, and to their use. In particular, the alkoxysilane-functionalized, allophanate-containing coating compositions include a) as a binder component, 10-99 wt % of at least one reaction product of i) at least one monourethane i) containing alkoxysilane groups and 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 ii) at least one diisocyanate ii), in a molar ratio of i) to ii) of from 3:1 to 1.5:1, preferably from 2.5:1 to 1.
