CROSSLINKABLE COMPOSITIONS AND THEIR USE OF THE PRODUCTION OF NON-STICK COATINGS Compositions which comprise (A) a polymeric organosilicon compound having 1 to 6 Si-bonded hydro gen atoms per molecule, (B) a polymeric organosilicon compound having at least two alkenyl groups per molecule and a viscosity of not more than 100 mm2/s, (C) a polymeric organosilicon compound having on average at least 10 Si bonded hydrogen atoms per molecule, (D) a catalyst and, optionally (E) an inhibitor, with the proviso that - the molar ratio of all the Si-bonded hydrogen atoms to all the SiC bonded alkenyl groups in the composition is on average less than 1, - the composition comprises (B) in an amount such that the composi tion comprises on average at least 1.1 alkenyl radicals of (B) per Si-bonded hydrogen atom of (A) - and the content of Si-bonded hydrogen atoms of (C) is 5% to 50%, based on the number of all the Si-bonded hydrogen atoms present.
