The present invention relates to compositions comprising a) 20-80% by weight, based on the total mass of constituents of the composition, of at least one sulfonic acid functionalized with at least one hydroxy and/or amino group and/or at least one sulfonic acid derivative functionalized with at least one hydroxy and/or amino group and b) 80-20% by weight, based on the total mass of constituents of the composition, of at least one compound having at least two OH groups, a method for the preparation thereof and use thereof.

Low-water-content hydrophilization agents and use thereof in aqueous dispersions

Crosslinkers based on alkoxysilanes and alkoxysilane mixtures containing an isocyanate group can be used as a starting component in the production of coating compositions or as paint binder component, or can be used with adhesive o sealant binders o binder components having g ups reactive toward alkoxysilane groups.

Low-viscosity crosslinkers containing alkoxysilane groups

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 R, Rand Rin each case independently of one another are a linear or branched and/or cyclic C1-C8 alkylene radical, R', R&#x2033; and R&#x2032;&#x2033; 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.

Hydrophilic, alkoxysilane-containing isocyanurates

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 1R(OR)Si&#x2014;R&#x2014;NH&#x2014;(C&#x2550;O)&#x2014;OR&#x2003;&#x2003;formula 1,where R, R, Rand Rare 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.
