Room-temperature-curable organopolysiloxane compositions

摘要

A highly storage-stable room-temperature-curable organopolysiloxane composition, that cures to yield a product whose surface resists staining and that does not cause staining of the neighboring regions of the substrate in contact with said cured product, is made from a polydiorganosiloxane having silanol or a silicon-bonded hydrolyzable group at both molecular chain terminals, with the proviso that this polydiorganosiloxane does not contain the imidazolinyl radical bonded to silicon; an imidazolinyl-functional organosiloxane having at least one imidazolinyl radical with the following general formula bonded to silicon wherein R<1> is a C1 to C50 divalent hydrocarbon radical, each R<2> is hydrogen atom or a C1 to C50 monovalent hydrocarbon radical, and R<3> is a C2 to C50 monovalent hydrocarbon radical having aliphatic unsaturation; a filler; and a crosslinking compound which is a Si-bonded hydrolyzable group-containing organosilane or organosiloxane oligomer.
