    • Provided is a room temperature curable organopolysiloxane composition, including (A) 100 parts by mass of a diorganopolysiloxane with both terminals blocked with silanol groups, or a diorganopolysiloxane with each terminal blocked, independently, with a trialkoxysilyl group or a dialkoxyorganosilyl group, or a mixture thereof, (B) 0.1 to 30 parts by mass of a silane compound and/or a partial hydrolysis-condensation product thereof containing an average of at least two hydrolysable groups bonded to silicon atoms within each molecule, and in which the remaining groups bonded to silicon atoms are methyl groups, ethyl groups, propyl groups, vinyl groups, or phenyl groups, and (C) 0.1 to 10 parts by mass of either one, or two or more organosilicon compounds containing amino groups, and also containing four or more hydrolysable groups. Also provided are a sealing material and an adhesive including the above composition. Further provided are a process for sealing an adherend with a cured product of the above sealing material and a process for bonding two adherends with a cured product of the above adhesive. The room temperature curable organopolysiloxane composition yields a cured product that exhibits excellent adhesion when exposed to hot water vapor and following such exposure, and suffers minimal evaporation residues derived from the cured product.
    • 提供了一种室温固化型有机聚硅氧烷组合物,其包含(A)100质量份两端用硅烷醇基封端的二有机聚硅氧烷,或每一末端用三烷氧基甲硅烷基或二烷氧基有机甲硅烷基封端的二有机聚硅氧烷,或混合物 (B)0.1〜30质量份的硅烷化合物和/或其部分水解缩合产物,其平均含有至少两个与每个分子中的硅原子键合的可水解基团,其中剩余的基团与 硅原子是甲基,乙基,丙基,乙烯基或苯基,和(C)0.1至10质量份的含有氨基的一种或两种以上有机硅化合物,并且还含有四种或更多种可水解的 团体 还提供了包括上述组合物的密封材料和粘合剂。 还提供了用上述密封材料的固化物密封被粘物的方法以及将两个被粘体与上述粘合剂的固化物接合的方法。 室温可固化的有机基聚硅氧烷组合物产生固化产物,当暴露于热水蒸气并经受这种暴露时,其表现出优异的粘附性,并且受到来自固化产物的最小的蒸发残余物的影响。
