Viscosity peaking during initial formulation of condensation curing compositions employing silanol-functional organopolysiloxanes and alkoxysilanes is avoided by employing specific titanium compounds. A curing catalyst which may be a titanium compound or a tin compound may be added following disappearance of silanol functionality.
