Patent ID: 7902269

Claim:
Condensation-crosslinking two-component dental material with a component A containing a) at least one alkoxysilyl-functional polyether which comprises besides the terminal alkoxy groups and the polyether groups a third structural unit of alkylene spacers, each located on the terminal alkoxysilyl groups, and as a fourth structural unit at least one of urethane groups and urea groups, wherein the individual structural units of the at least one polyether a) are arranged according to at least one of wherein R 1 , R 2 , and R 3 independently of one another are alkoxy, alkyl, aryl, aralkyl, alkylaryl groups, or hydrogen, provided that at least one of the aforementioned residues is an alkoxy group, and x=1 to 6, n=1 to 6, and m=1, and wherein R 1 , R 2 , and R 3 independently of one another are alkoxy, alkyl, aryl, aralkyl, alkylaryl groups, or hydrogen, provided that at least one of the aforementioned residues is an alkoxy group, and x=1 to 6, n=1 to 6, and l=1, and a component B containing b) at least one catalyst and c) water, wherein the at least one catalyst b) is a salt that is formed from at least one cation selected from cations formed by protonation of a base with a pK BH+ value of at least 21 measured in acetonitrile, wherein the base has at least one structural unit according to the general formula I and/or according to the general formula II and/or according to the general formula III and at least one anion of branched carboxylic acid with a length of the (cyclo)alkyl chain provided on the carboxyl group of at least 3 carbon atoms, or an unbranched carboxylic acid with a length of the (cyclo)alkyl chain provided on the carboxyl group of at least 5 carbon atoms, wherein the dental material has a maximum setting time in a patient's mouth of 10 minutes as determined according to ISO 4823, 1992 version.
