Guanidingruppen containing semi-organic silicon group-containing compounds, their use for curing compounds containing alkoxysilyl groups, compositions containing the curing catalysts of the invention and use of the compositions as adhesives and sealants and as coating compositions. Claimed is a general formula (I) for polysiloxanes containing guanidine groups (M G , D G ) M a M G b D c D G d T e Q f (I) a = 0 to 10, b = 0 to 10, c = 0 to 350, d = 0 to 50, e = 0 to 50, f = 0 to 10, wherein the sum of the indices b and d is equal to or greater than 1 to 20, with the proviso that for the index a is equal to 2 and at the same time the sum of the indices of b, c, e and f is zero, then the index d is not equal to 1, or provided that for the sum of the indices of a, c, d, e, and f equal zero then the index b is greater than 1, M = [R 3 SiO 1/2 ] M G = [R G R 2 SiO 1/2 ], D = [R 2 SiO 2/2 ], D G = [R G 2 SiO 2/2 ], T = [RSiO 3/2 ], Q = [SiO 4/2 ]. |
