    摘要： A room-temperature-curable organopolysiloxane composition for an oil seal, wherein an organosilane compound containing a specific organo-oxymethyl group and represented by formula (1) and/or a partial hydrolysis condensate of said compound is used as a curing agent (crosslinking agent), and an organic compound having a guanidine skeleton is added in combination as a curing catalyst.

    (In the formula, each R 1 is independently a C1-12 unsubstituted or substituted monovalent hydrocarbon group, R 2 is a C1-12 unsubstituted or substituted monovalent hydrocarbon group, Y is a hydrolyzable group, and n is 0, 1 or 2.)
    It is thus possible to obtain a cured product having good rubber properties, adhesiveness, and engine oil resistance after curing even without containing a metal-based catalyst.
