ABSTRACT:
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"?R1NH2 (2)in-line-formulae description="In-line Formulae" end="tail"?(wherein, R1represents 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"?H2N—R2—NH2 (3)in-line-formulae description="In-line Formulae" end="tail"?(wherein, R2represents 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.
