Curable composition for forming low bleeding gel type cured product
摘要：
A curable composition comprising:(A) a branched polyfluorodialkenyl compound represented by a general formula (1): CH2═CH—(X)a-Rf1-(X′)a—CH═CH2  (1) wherein, X and X′ are bivalent groups such as —CH2— and —CH2O—, a represents, independently, either 0 or 1, and Rf1 is a specific bivalent fluorine-containing group, (B) a branched polyfluoromonoalkenyl compound represented by a general formula (2): Rf2-(X′)a—CH═CH2  (2) wherein, X′ and a are as defined above, and Rf2 is a specific fluorine-containing group, (C) an organohydrogensiloxane compound with at least two hydrogen atoms bonded to silicon atoms, and (D) a platinum group metal catalyst; as well as a low bleeding gel type cured product obtained by curing such a composition, and an electrical or electronic component sealed or encapsulated using such a cured product. The gel type cured product displays very little bleeding of free oil constituents from the gel as a result of stress such as pressure fluctuation or heat history.
摘要（中）：

一种可固化组合物，其包含：（A）由通式（1）表示的支链多氟联苯基化合物：<？in-line-formula description =“In-line formula”end =“lead”？> CH 2 （X）a - （X）a - （X'）a-CH 2 CH 2 >（1）<？in-line-formula description =“In-line Formulas”end =“tail”？>其中X和X'是二价基团，例如-CH 2 - CH 2 O-，a独立地表示0或1，Rf 1是特定的二价含氟基团，（B）支化多氟单链烯基化合物 通式（2）：<？in-line-formula description =“In-line formula”end =“lead”？> Rf <2> - （X'） > -CH-CH 2（2）<？in-line-formula description =“In-line formula”end =“tail”？>其中，X'和a如上定义，和 Rf 2是特定的含氟基团，（C）具有至少两个与硅原子键合的氢原子的有机氢硅氧烷化合物，和（D）平台 inum组金属催化剂; 以及通过固化这种组合物获得的低出血凝胶型固化产物，以及使用这种固化产物密封或包封的电气或电子部件。 由于应力如压力波动或热历史，凝胶型固化产物显示出很少的游离油成分从凝胶中渗出。
