The present invention relates to new organosilane esters which can be characterized by the formula Y-(CH2)nSi(CH3)p-XmZ3-(m+p). In this formula, Y represents either a substituted or unsubstituted amino group, or it represents the mercapto moiety or the moiety <IMAGE> X represents an alkoxy group with 1 to 4 carbon atoms and Z a glycol ether moiety. The index n can assume the numerical values from 1 to 3, m can be 0 or 1 and p can be 0 or 1 or 2, on the condition that m+p is equal to or less than 2. The new silanes yield very stable hydrolyzates and have good adhesion-improving properties. They are therefore particularly well suited for use in sealing compositions.
