摘要： The present novel organosilicon compound is a 2-trimethoxysilylpropionate represented by the following formula ##STR1## wherein R represents a monovalent hydrocarbon group having 6 to 12 carbon atoms. This ester reacts efficiently with alcohols and silanols and is useful, for example, as a terminal alkoxysilylating agent for organopolysiloxanes such as industrially useful .alpha.,.omega.-dihydroxypolydimethylsiloxane, or as a surface treatment for silicas, or as a storage stabilizer that serves as a scavenger of an alcohol for alcohol elimination type RTV. Further, since the present organosilicon compound is a three-functional alkoxysilane having three methoxy groups in the molecule, it is useful as a curing agent for alcohol elimination type RTV.

摘要： A room temperature curable rubber composition of a condensation curing type that comprises as a base polymer a diorganopolysiloxane or a polyoxyalkylene in which both ends of the molecular chain are blocked with a hydrolyzable silyl group, and a .beta.-dicarbonyl compound and an amino group containing organic compound that are blended with the base polymer. Since the room temperature curable rubber composition is cured with water in the air and at the same time the dehydration condensation of the .beta.-carbonyl group and the amino group produces water in the composition, the quick curability and deep curability are improved remarkably. In addition, since this dehydration condensation reaction is an irreversible reaction, the product produced by the condensation dehydration is hydrolyzed to prevent the amino group containing compound from being regenerated, and as a result the hydrophilic nature of the cured product is prevented from increasing not to damage the water resistance.
摘要翻译：一种缩合固化型室温可固化橡胶组合物，其包含作为基础聚合物的二有机聚硅氧烷或分子链两端用可水解甲硅烷基封端的聚氧化烯，以及β-二羰基化合物和含氨基的有机物与基础聚合物共混的化合物。由于室温固化橡胶组合物在空气中用水固化，同时β-羰基和氨基的脱水缩合在组合物中产生水，因此快速固化性和深度固化性显着提高。此外，由于该脱水缩合反应是不可逆反应，所以通过缩合脱水生成的产物被水解以防止含氨基化合物再生，结果，防止了固化产物的亲水性增加，不会增加损坏防水性。
