    Abstract: Curable compositions are disclosed, containing at least one organopolysiloxane, which contains at least one hydroxyl group and/or group which can be hydrolyzed, in aqueous dispersion, i) at least one oganopolysiloxane having a dynamic viscosity of 0.05 to 7 (measured according to Brookfield DV-II+, spindle 3, 23° C.), which is free of hydroxyl groups and/or groups which can be hydrolyzed, in aqueous dispersion, at least one cross-linking agent, at least one emulsifier, at least one cross-linking catalyst, at least one aqueous silicon-free polymer dispersion, at least one filler, and optionally water. The compositions are suitable as sealants, adhesives, or coating agents for application in the construction field, in particular in the sanitary field and in the kitchen field. They are characterized in relation to aqueous silicone preparations known up to this point by an improved adhesion spectrum, in particular on plastic substrates.
