Abstract

The present invention relates to compounds containing alkoxysilane and hydantoin groups and corresponding to the formula ##STR1## wherein X represents identical or different organic groups which are inert to isocyanate groups below 100.degree. C., provided that at least one of these groups is an alkoxy group, PA1 Z represents COOR.sub.1 or an aromatic ring, PA1 R represents the residue obtained by removing the isocyanate groups from an organic monomeric polyisocyanate, a polyisocyanate adduct or an NCO prepolymer, PA1 R.sub.1 represents an organic group which is inert to isocyanate groups at a temperature of 100.degree. C. or less, PA1 R.sub.3 and R.sub.4 are identical or different and represent hydrogen or organic groups which are inert to isocyanate groups at a temperature of 100.degree. C. or less, PA1 n is an integer from 1 to 8 and PA1 m has an average value of 1.5 to 6. The present invention also relates to the use of these compounds for the preparation coatings, sealants and adhesives.
