摘要

Process for coating a surface with an organosiloxane composition to render it non-adherent. The organosiloxane composition is substantially solvent-free, has a viscosity not exceeding 4000 cS at 25 DEG C and comprises (1) a polydiorganosiloxane having silicon-bonded vinyl radicals (2) an organohydrogenpolysiloxane and (3) a catalyst which is RhX3(SR2)3 or Rh2(CO)4X2 in which X is halogen, preferably chlorine, and each R is alkyl, aryl, aralkyl, alkaryl or R'3SiQ wherein Q is a divalent aliphatic hydrocarbon radical and R' is alkyl, aryl, aralkyl or alkaryl or (CH3)3Si-. After application the composition is cured.
