摘要: Provided is an alkoxysilyl-vinylene group-containing silicon compound represented by the following general formula (1):
wherein each of R 1 and R 2 independently represents a monovalent hydrocarbon group having 1 to 20 carbon atoms; R represents a monovalent hydrocarbon group having an organic functional group(s) and 1 to 30 carbon atoms; and n represents an integer of 1 to 3.
The alkoxy groups in the novel organic silicon compound of the invention have a dramatically improved hydrolyzability. Further, a high adhesion or adhesiveness; and a fast adhesiveness can be exhibited by adding the novel organic silicon compound to a room temperature curable organopolysiloxane.摘要翻译: 提供由以下通式(1)表示的含烷氧基甲硅烷基 - 亚乙烯基的硅化合物:其中R 1和R 2各自独立地表示具有1至20个碳原子的一价烃基; R表示具有有机官能团和1〜30个碳原子的一价烃基; n表示1〜3的整数。本发明的新型有机硅化合物中的烷氧基具有显着提高的水解性。 此外,粘合性或粘合性高; 并且通过将新的有机硅化合物加入到室温可固化的有机聚硅氧烷中可以显示出快速的粘附性。

摘要: The present invention pertains to a room-temperature-curable organopolysiloxane composition containing (A) an organopolysiloxane having the hydrolysable silyl-group-containing monovalent organic group represented by formula (1)
(R 1 represents a substituted or unsubstituted C1-10 alkyl group or a substituted or unsubstituted C6-10 aryl group, R 2 represents a substituted or unsubstituted C1-10 alkyl group or a substituted or unsubstituted C6-10 aryl group, and R 3 represents a substituted or unsubstituted CI-20 alkyl group or a hydrogen atom; M is an integer from 1 to 3, and n is an integer of 2 or more; and the broken line represents atomic bonding), (B) a hydrolysable organosilane compound and/or a partially hydrolysed condensate thereof, (C) a curing catalyst, and (F) a bleed oil. According to this configuration, an organotin-compound-free and MEKO-free product is achieved, exceptional fast-curing properties are achieved, and a cured coating film has exceptional rubber strength and exceptional antifouling performance over a long period of time.-

摘要: Through the present invention, by undergoing a step in which a straight-chain diorganopolysiloxane having silanol groups at both terminal ends of the molecular chain thereof, a hydrolysable silane and/or a partial hydrolysis condensate thereof having a hydrolysable group capable of detaching a lactic acid ester, and an amino-group-containing hydrolysable organosilane and/or a partial hydrolysis condensate thereof are pre-mixed/reacted in advance and silanol groups at both terminal ends of the molecular chain of a main agent (base polymer) are blocked by specific hydrolysable silyl groups, it is possible to manufacture a lactic-acid-ester-type room-temperature-curable organopolysiloxane composition excellent in all characteristics including curability, adhesive properties, workability, and the like that were not attainable by the conventional lactic-acid-ester-type room-temperature curable (RTV) silicone rubber composition.

摘要: A room-temperature-curable silicone coating composition comprising
(A) an organopolysiloxane resin of a three-dimensional net structure which has an R 3 SiO 1/2 /SiO 4/2 molar ratio of 0.5-1.5, contains a given amount of silanol groups, and has a molecular weight of 2,000-10,000,
(B) a silane compound having three or more hydrolyzable groups in the molecule and/or a product of partial hydrolytic condensation of the silane compound,
(C) a linear diorganopolysiloxane in which both ends of the molecular chain have been blocked with silanol groups, and
(D) a moisture-curing initiator comprising an oligomer of an organotitanium compound, the room-temperature-curable silicone coating composition giving a cured object having a durometer A hardness of 50 or greater.
This composition can be an alcohol elimination type room-temperature-curable silicone coating composition which can be easily produced at low cost, has excellent long-term storage stability, and gives high-hardness cured objects (coating films), the cured coating films combining transparency with heat resistance. -
