摘要： The silicone composite product comprises a silicone gel obtained by curing a specified addition-curable type organopolysiloxane composition, and an elastomer layer or resin layer formed on the silicone gel by use of an organopolysiloxane having Si-bonded alkenyl groups and Si-bonded hydrogen atoms. The silicone composite product has the elastomer layer or resin layer formed integrally with the silicone gel phase, whereby such problems as adhesion of dust or refuse to the surface of the silicone gel, etc. can be solved effectively.

摘要： A silicone composition comprising, as the base component to provide crosslinking points, an organopolysiloxane copolymer comprising diorganosiloxane blocks and trifunctional arylsiloxane blocks and the molecular ends of which are terminated with alkenylsiloxy units. This base component is combined with an organohydrogenpolysiloxane and an addition reaction catalyst. This silicone composition can be hardened to produce a highly elastic and damping material which makes an ideal damping and earthquake-resistant structure.

摘要： A room temperature-curable fluorosilicone rubber composition is disclosed, which is capable of giving a cured silicone rubber having excellent resistance against organic solvents and petroleums withhigh curability despite the high fluorine content which may cause steric hindfrance against the curing reaction due to the bulkiness of the fluorine-containing substituent groups. Different from conventional fluorine-containing diorganopolysiloxanes, in which the fluorine-containing substituent groups are bonded to the silicon atoms at random positions throughout the molecule, several silicon atoms from each of the molecular chain ends of the diorganopolysiloxane as the principal ingredient of the inventive composition are free from fluorine-containing substituent groups so that the crosslinking reaction with the silanolic hydroxy groups bonded to the terminal silicon atoms is not disturbed by the fluorine-containing groups in the vicinity of the terminal silanol groups.
摘要翻译：公开了一种室温可固化的氟硅橡胶组合物，其能够提供具有优异的耐有机溶剂和具有高固化性的石油的固化的硅橡胶，尽管氟含量高，这可能导致固化反应的空间阻碍，这是由于含氟取代基。与常规含氟二有机聚硅氧烷不同，其中含氟取代基在整个分子的随机位置键合到硅原子上，作为本发明组合物的主要成分的二有机聚硅氧烷的每个分子链末端的几个硅原子不含氟取代基，因此与末端硅原子键合的硅烷醇羟基的交联反应不会受到末端硅烷醇基附近的含氟基团的干扰。

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 fluorine-substituted organopolysiloxane as the principal ingredient of the inventive silicone rubber composition has vinyl groups to serve as the cross-linking points at the molecular chain terminals while at least the penultimate siloxane unit or the silicon atom adjacent to the terminal silicon atom has no fluorine-substituted hydrocarbon group bonded to the silicon atom. Being freed from the steric hindrance due to the bulky fluorine-substituted hydrocarbon group bonded to the adjacent silicon atom, the vinyl group bonded to the terminal silicon atom can pertain to the cross-linking reaction much easier than otherwise so that the silicone rubber composition of the invention containing an organic peroxide or a combination of an organohydrogenpolysiloxane and a platinum catalyst as a curing agent can be rapidly cured to give a cured silicone rubber article having excellent resistance against oils and organic solvents as well as mechanical properties.
摘要翻译：作为本发明的硅橡胶组合物的主要成分的氟取代的有机聚硅氧烷具有乙烯基作为分子链末端的交联点，而至少倒数第二硅氧烷单元或与末端硅原子相邻的硅原子没有与硅原子键合的氟取代烃基。由于与相邻的硅原子键合的大体积的氟取代烃基而消除空间位阻，与末端硅原子键合的乙烯基可以与其它方式相容容易，因此硅橡胶组合物包含有机过氧化物或作为固化剂的有机氢聚硅氧烷和铂催化剂的组合的本发明可以快速固化，得到具有优异的耐油性和有机溶剂性的固化的硅橡胶制品以及机械性能。
