Abstract: New carbofunctional organosilanes which may be regarded as alkoxysilyl- and glycidyl ether-substituted carbamate-modified urea derivatives having the formula

are obtained by reacting an aminomethyl-alkoxysilane of the formula

with an epoxy-organo-isocyanate of the formula

at a temperature below 50*C. In these formulae R is alkyl; R'' is alkyl, cyclohexyl or phenyl; R'''' is alkylene or cycloalkylene; n is 1, 2 or 3. The products are utilizable for priming silicious surfaces and for cross-linking convertible organopolysiloxanes.
