Abstract

L'invention se rapporte aux silicones. Elle concerne une composition durcissable améliorée comprenant un mélange de : a. Un polyorganosiloxane contenant de 67 à 85 moles p. cent d'unités C6 H 5 SiO3/2 et 33 à 15 moles p. cent d'unités CH2 =CH(CH3 ) 2 SiO1/2 , ce polyorganosiloxane ayant au moins 8 atomes de silicium par molécule; b. Un agent de réticulation pour a. formé d'un polysiloxane contenant des groupes cong SiH, b étant présent en une proportion suffisante pour donner environ 0,9 à 1,1 mole de groupes cong SiH par mole de groupes CH2 =CHSi cong présents dans a et c. Un catalyseur au platine; d. Un diluant réactif répondant à la formule : ØCH2 = CH(CH3 )2 SiOõ 2 Si(C6 H5 )2 Utilisation comme résine à couler.The invention relates to silicones. It relates to an improved curable composition comprising a mixture of: a. A polyorganosiloxane containing 67 to 85 moles p. hundred of C6 H 5 SiO3 / 2 units and 33 to 15 moles p. one hundred units of CH2 = CH (CH3) 2 SiO1 / 2, this polyorganosiloxane having at least 8 silicon atoms per molecule; b. A crosslinking agent for a. formed from a polysiloxane containing cong SiH groups, b being present in an amount sufficient to give about 0.9 to 1.1 moles of cong SiH groups per mole of CH2 = CHSi cong groups present in a and c. A platinum catalyst; d. A reactive diluent corresponding to the formula: ØCH2 = CH (CH3) 2 SiOõ 2 Si (C6 H5) 2 Use as casting resin.
