A room temperature curable organopolysiloxane composition is provided. It includes (A): a diorganopolysiloxane containing 2 hydroxyl groups or hydrolysable groups bonded to silicon atoms within each molecule; (B): (B1) an amine compound of the general formula (2): <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>NH<SUB>2</SUB> (2)<?in-line-formulae description="In-line Formulae" end="tail"?> (wherein, R<SUP>1 </SUP>represents a monovalent hydrocarbon group of 12 to 30 carbon atoms), and/or an amine compound of the general formula (3): <?in-line-formulae description="In-line Formulae" end="lead"?>H<SUB>2</SUB>N-R<SUP>2</SUP>-NH<SUB>2</SUB> (3)<?in-line-formulae description="In-line Formulae" end="tail"?> (wherein, R<SUP>2 </SUP>represents a bivalent hydrocarbon group of 4 to 30 carbon atoms), or (B2) a compound which, via a hydrolysis reaction, is capable of yielding an amine compound of (B1); (C) a cross-linking agent; and (D) a curing catalyst. The composition, following curing, generates a silicone rubber to which a coating can be easily applied, and in which that coating is not easily removed.
