ABSTRACT:
The room temperature-curable (RTV) organopolysiloxane composition of the invention comprises, in addition to the conventional components of a diorganopolysiloxane terminated at both molecular chain ends each with a silanolic hydroxy group, a hydrolyzable organosilicon compound having two or more hydrolyzable groups in a molecule and a filler, an organosilicon-modified polyoxyalkylene compound, of which the organosilicon-containing terminal groups have at least one hydrolyzable group so as to pertain to the crosslinking reaction in its part. By virtue of this unique additive component, the composition is quite free from the disadvantage of sagging when the composition is applied to building works and the like and still retains excellent adhesive properties to the substrate surface in contrast to the difficulty in the conventional RTV compositions in which reducing of the phenomenon of sagging and retention of the strong adhesive strength are hardly compatible.
