Room temperature curable organopolysiloxane composition

Claim 1

A room temperature curable organopolysiloxane com­position comprising: (A) 100 parts by weight of a diorganopolysiloxane having a hydroxyl group at both teminal ends of its molecular chain, or 2 or 3 C₁-C₄ alkoxy groups at each terminal end of its molecular chain; (B) 1 to 400 parts by weight of a filler; (C) 0 to 50 parts by weight of an alkoxysilane represented by the general formula (I): (R¹) m Si(OR²) 4-m (I) where R¹ is a substituted or unsubstituted C₁-C₂₀ monovalent hydrocarbon groups, R² is a C₁-C₄ alkyl group or a C₂-C₄ alkoxyalkyl group, m is an integer of 0 or 1, or a partial hydrolysis product thereof; (D) 0.01 to 10 parts by weight of an organosilicon compound having at least one group represented by the gen­eral formula (II): [(R³)₂N]₂C=N-      (II) where R³ is a hydrogen atom or a C₁-C₆ monovalent hydrocarbon group, in its molecule; (E) 0.01 to 10 parts by weight of an organic tin compound; (F) 0.1 to 20 parts by weight of an organosilicon compound having at least one group represented by the gen­eral formula (III): where R⁴ is a substituted or unsubstituted C₁-C₂₀ monovalent hydrocarbon group, or a substituted or un­substituted phenyl group, R⁵ and R⁶ are each a hydrogen atom, methyl or ethyl group, and n is an integer of 0, 1 or 2.
