Abstract

A room-temperature-curable polyorganosiloxane composition includes: 100 parts by mass of polyorganosiloxane capped with hydroxyl groups at termini and having a viscosity (23° C.) of 0.02 to 1000 Pa·s; 1 to 200 parts by mass of a filler capable of imparting flame retardancy; 0.1 to 10 parts by mass of a partially hydrolyzed condensate of a silane compound of R¹_aSi(OR²)_4-a wherein R¹('s) and R²('s) independently represent a substituted/unsubstituted univalent hydrocarbon group, and ‘a’ represents a numerical value of 0≦a≦0.2 on average; 0.1 to 10 parts by mass of a silane compound of R³₂Si(OR⁴)₂ wherein R³'s and R⁴'s) independently represent a substituted/unsubstituted univalent hydrocarbon group, or its partially hydrolyzed condensate having 3 or less Si atoms in its molecule; 0.1 to 10 parts by mass of an amine-functionalized silane compound of (R⁵O)₃Si—R⁶—NH—R⁷ wherein R⁵'s independently represent a substituted/unsubstituted univalent hydrocarbon group, R⁶ represents a substituted/unsubstituted bivalent organic group, and R⁷ represents a hydrogen atom, a substituted/unsubstituted univalent hydrocarbon group, or an aminoalkyl group; 0.001 to 10 parts by mass of a curing catalyst; and 1 to 1000 ppm of a platinum compound (in terms of the Pt content).
