Room-temperature curable polyorganosiloxane composition

摘要

A room-temperature curable polyorganosiloxane composition comprising the following components (A) to (C): (A) 100 parts by weight of (1) a mixture of a terminally reactive polyorganosiloxane represented by the formula R1a(R2O)3-aSiZ[R2SiO]nSiR 12ZSi(OR2)3-aR1a; (2) a silane represented by the formula R3bSi(OR4)4-b or a partially hydrolyzed condensation product thereof; the amount of (A) (1) being from 85 to 100 parts by weight; (B) from 0.01 to 20 parts by weight of a curing catalyst; and (C) from 0.5 to 20 parts by weight of a polycondensation reaction product of an amino group-containing silane represented by the formula XcSi(WNH2)Y3-c and a silazane represented by the formula XdY3-dSiNHSiY3-dXd; where all symbols are defined in the specification.
