Abstract
The present invention relates to silicone compositions which comprise at least one ketoximosilane-terminated polydiorganosiloxane and also at least one alkoxysilane. These compositions are neutrally crosslinking and combine a low odour with high adhesion and good storage stability.
Claims16
A silicone composition comprising
- (a) at least one ketoximosilane-terminated polydiorganosiloxane of the general formula (I)
- where
- R1 and R1′ independently are each an unsubstituted or substituted alkyl or alkenyl or aryl radical;
- R2 independently at each occurrence is an unsubstituted or substituted alkyl or alkenyl or aryl radical;
- R3 and R4 are each an alkyl radical;
- n stands for values from 20 to 3000;
- and m is either 0 or 1;
- (b) at least one alkoxysilane of the general formula (II)
- (R5)pSi(OR6)4-p (II)
- where
- R5 independently at each occurrence is an unsubstituted or substituted alkyl or alkenyl or aryl radical or a radical of the formula —(R7—O)q—R8,
- where R7 is alkylene and R8 is an alkyl radical, and q stands for a value between 1 and 5,
- R6 independently at each occurrence is H or is an alkyl radical,
- and p is either 0 or 1.
