Multicomponent room temperature-curable organopolysiloxane composition, cured product of said composition, and molded product comprising said cured product

A room temperature-curable organopolysiloxane composition comprising:

• (A) an alkoxysilyl-ethylene group-terminated organopolysiloxane having in one molecule at least one group represented by the following structural formula (1)
• wherein R1 represents an alkyl group that has 1 to 20 carbon atoms and may have one or more substituent groups, and when said alkyl group has 3 or more carbon atoms it may be a cycloalkyl group;
• R2 represents a hydrocarbon group that has 1 to 20 carbon atoms and may have one or more substituent groups;
• a represents an integer of 1 to 3;
• and n represents an integer of 0 to 10;
• (B) an organopolysiloxane in an amount of 10 to 250 parts by mass with respect to 100 parts by mass of said component (A), and represented by the following general formula (2)
• wherein R2 represents a hydrocarbon group that has 1 to 20 carbon atoms and may have one or more substituent groups;
• and m represents a number at which the organopolysiloxane exhibits a viscosity of 10 to 1,000,000 mPa·s at 25° C.;
• and
• (C) a curing catalyst in an amount of 0.001 to 20 parts by mass with respect to 100 parts by mass of said component (A).
