The invention relates to addition-crosslinkable silicone compositions which comprise: (A) diorganopolysiloxane(s) with a viscosity of from 10 to 40,000 Pa.s determined at 25° C., composed of two units of the general formula (1)<paragraph lvl="0"><in-line-formula>[R2R1SiO1/2] (1),</in-line-formula>units of the general formula (2)<paragraph lvl="0"><in-line-formula>[R2SiO2/2] (2), and</in-line-formula>from 0 to 0.3 % by weight of units of the general formula (3)<paragraph lvl="0"><in-line-formula>[RR1SiO2/2] (3),</in-line-formula>(B) from 0.05 to 25% by weight, based on the sum of the weights of diorganopolysiloxane (A) and diorganopolysiloxane(s) (B), of diorganopolysiloxane(s) with a viscosity of from 60 to 2 000 mPa.s, determined at 25° C., composed of 2 units of the general formula (1), and units of the general formula (2), (C) an SiH-functional crosslinker, and (D) a hydrosilylation catalyst, wherein R is an optionally substituted hydrocarbon group and R1 is an unsaturated, optionally substituted hydrocarbon group.
