• Subjects: ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAININGELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN,SULFUR, SELENIUM OR TELLURIUM; CHEMISTRY; COMPOSITIONS BASED THEREON; MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONSONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS; METALLURGY; ORGANIC CHEMISTRY; ORGANIC MACROMOLECULAR COMPOUNDS; THEIR PREPARATION OR CHEMICAL WORKING-UP

The present invention relates to aqueous solutions or dispersions of compounds, which contain 0.5 to 6% by weight of alkoxysilane and/or silanol groups (calculated as Si, MW 28), based on the weight of the compounds containing alkoxysilane groups, and are substantially free from isocyanate groups and chemically incorporated hydrophilic groups, wherein the alkoxysilane groups are initially incorporated by the reaction of a polyisocyanate with an amino compound corresponding to formula I wherein X represents identical or different organic groups which are inert to isocyanate groups below 100 DEG C, provided that at least one of these groups is an alkoxy group, Y represents a linear or branched alkylene group having 1 to 8 carbon atoms and R1 represents an organic group which is inert to isocyanate groups at a temperature of 100 DEG C or less. The present invention also relates to coating, adhesive or sealing compositions containing these aqueous compounds as the binder.
