A process for producing a room temperature vulcanizable organopolysiloxane
composition comprising:
(A) 100 parts by weight of a diorganopolysiloxane having in one molecule
at least two hydroxyl groups and/or hydrolyzable groups connecting to
silicon atoms;
(B) 0.2 to 10 parts by weight of an alkylene oxide compound having silicon
atoms in a molecule;
(C) 0.5 to 100 parts by weight of a silica; and
(D) 0.5 to 30 parts by weight of a silane and/or condensate of partial
hydrolyzate thereof,
wherein said process comprises steps of hot-mixing component (A),
component (B), and component (C) together, and subsequently mixing
component (D) thereto.
