TWO-PART TYPE CONDENSATION-CURABLE ORGANOPOLYSILOXANE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a two-part type condensation curable organopolysiloxane composition where the first agent can be easily mixed with the second agent, in equivalent amounts, and is excellent in fast curability as well as the curability in a deep portion.;SOLUTION: The two-part type condensation curable organopolysiloxane composition comprises: the first agent containing (A) 100 pts.mass of a diorganopolysiloxane having both ends terminated with a hydroxy group, (B) 0.5-10 pts.mass of a silane and/or siloxane having ≥3 alkenoxysilyl groups in its molecule, and (C) 0.01-10 pts.mass of a curing catalyst; and the second agent containing (D) a diorganopolysiloxane having both ends terminated with a hydroxy group and no silane and/or siloxane of component (B), wherein the mass ratio of the first agent to the second agent is in a range of 25:75-75:25.;COPYRIGHT: (C)2010,JPO&INPIT
