Abstract:
A moisture-curable compound which hasa) a content of aromatically-bound isocyanate groups (calculated as NCO, MW 42) of 0.2 to 30% by weight,b) a content of alkoxysilane groups (calculated as Si, MW 28) of 0.2 to 4.5% by weight andc) an equivalent ratio of aromatically-bound isocyanate groups to alkoxy groups, which are bound to Si, of 1.0:0.05 to 1.0:1.4,wherein the preceding percentages are based on the weight of the moisture-curable compound and wherein the alkoxysilane groups are incorporated as the reaction product of a polyisocyanate with an amino compound corresponding to formula I ##STR3## 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,Y represents a linear or branched alkylene radical containing 1 to 8 carbon atoms,Z represents COOR.sub.1 or an aromatic ring,R.sub.1 and R.sub.2 are identical or different and represent organic groups which are inert to isocyanate groups at a temperature of 100.degree. C. or less andR.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.
