    摘要： A curable organopolysiloxane composition comprising a vinyl-containing organopolysiloxane, organohydrogenpolysiloxane and platinum catalyst is proposed which is cured into a gel-like material suitable as a potting and encapsulating agent for protecting, for example, electronic components from mechanical shocks and adverse influence of the ambient atmosphere. Different from conventional similar compositions, the gelled material from the inventive composition little suffers from the problem of bleeding of oily materials contained therein on the surface. This unique advantage is obtained by using, in place of the conventional vinyl-containing organopolysiloxanes in which the vinyl groups are bonded to the silicon atoms at random position in the molecular chain, a combination of two vinyl-containing organopolysiloxanes having a specified viscosity in a limited proportion, of which one has two and only two vinyl groups in a molecular each bonded to one of the silicon atoms at the molecular chain ends and the other has one and only one vinyl group in a molecule bonded to one of the silicon atoms at the molecular chain ends alone. The composition may further contain a low-viscosity dimethylpolysiloxane so that the silicone gel can be imparted with softness and adhesiveness without increasing the amount of bleeding of the oily constituents.

    摘要： The organopolysiloxane composition is useful as a potting or encapsulating material having a gel-like consistency for protecting electronic components even at an extremely low temperature as is encountered in the space industry. The composition is basically of the type in which crosslinks are formed by the addition reaction between silicon-bonded vinyl groups in an organopolysiloxane and silicon-bonded hydrogen atoms in an organohydrogenpolysiloxane but the outstanding cold resistance of the gel-like material obtained from the composition is imparted by incorporating specific silethylene-containing units of the unit formula OSiMe--CH.sub.2 CH.sub.2 --SiMe.sub.2 O.sub.0.5 into the organopolysiloxane in a specified molar content.

    摘要： Curable or vulcanizable fluorinated silicone compositions which comprise a uniform mixture of predetermined amounts of an organopolysiloxane of the following average unit formula ##STR1## in which R.sup.1 represents a monovalent hydrocarbon group having from 1 to 8 carbon atoms, and a and b are, respectively, a defined value; an organohydrogenpolysiloxane having at least three SiH groups in one molecule and consisting of the several siloxane units; and a catalytic amount of a platinum compound. If necessary, another type of polysiloxane may be added to the above composition in order to further improve physical properties. The composition is rapidly vulcanized to give a cured product having stable physical properties within a short time.
