ABSTRACT:
Multi-armed silyl polyalkoxylates of the formula (I), (H-A)n-Z-[A-B—Si(OR1)r(R2)3−r]m(I), where Z is an (m+n)-valent radical having at least three carbon atoms, A is a divalent polyoxyalkylene radical, B is a chemical bond or a divalent organic radical having 1 to 50 carbon atoms, OR1is a hydrolysable group, R1and R2independently of one another are a linear or branched alkyl group having 1 to 6 carbon atoms and r is an integer from 1 to 3, and m is an integer ≈1 and n is 0 or an integer ≈1, and m+n has a value from 3 to 100, for reducing glass corrosion and/or for improving the drying performance during mechanical cleaning of a glass surface. Also compositions, in particular for the cleaning of glass surfaces, which compositions contain compounds of the formula (I).
