Abstract
The present room temperature curing composition comprises an organopolysilethylenesiloxane represented by the following general formula: ##STR1## wherein R.sup.1 to R.sup.4 each represent an alkyl having up to 8 carbon atoms or a phenyl group and n is an integer of 10 or above, and an organosilane or an organosiloxane having two or more hydrolyzable groups such as alkoxy groups in the molecule. The composition can form a cured product high in rubber strength and excellent in chemical resistance.

A room temperature curing composition comprising
- (A) an organopolysilethylenesiloxane whose both ends are blocked with hydroxyl groups, represented by the following general formula [I]:
- ##STR25## wherein R.sup.1 to R.sup.4, which may be the same or different, each represent an unsubstituted or substituted monovalent hydrocarbon group having 1 to 10 carbon atoms and n is an integer of 10 or above
- and
- (B) at least one compound selected from the group consisting of organosilanes and organosiloxanes having two or more hydrolyzable groups in the molecule.
