ABSTRACT:
The invention provides storage-stable compositions of organosilicon compounds which comprise(A) organosilicon compounds which are selected from silanes (A1) of the formula 1in-line-formulae description="In-line Formulae" end="lead"?RxSi(OR1)4−x  (1)in-line-formulae description="In-line Formulae" end="tail"?and resinous organopolysiloxanes (A2) which contain units of the formulaRa⁡(R1⁢O)y⁢⁢Si⁢⁢O4-(a+y)2(2)and bear groups selected from hydroxyl groups bonded to silicon atoms and C1to C18hydrocarboxy groups bonded to silicon atoms, whereR is a hydrogen atom or monovalent SiC-bonded, optionally substituted C1-18hydrocarbon radicals,R1is a hydrogen atom or monovalent SiC-bonded, optionally substituted C1-18hydrocarbon radicals,x is 0, 1, 2 or 3,a is 0 or 1 andy is 1, 2 or 3, and(B) from 1 to 499 ppm by weight, based on the organosilicon compounds (A), of at least one amino-containing compound.
