Abstract
An adhesive polyorganosiloxane composition suitably employable as a sealant for joint portions of buildings, constructions, etc. which comprises: (A) a polydiorganosiloxane being end-blocked by silanol group and having the viscosity of 100-200,000 cSt at 25.degree. C.; (B) an aminoxy group-containing organosilicon compound having organoaminoxy groups of more than 2 per a molecule on the average; (C) an inorganic filler; and (D) a monovalent alcohol having the formula R--OH, in which R is a primary or secondary hydrocarbon group selected from the group consisting of a monovalent saturated aliphatic hydrocarbon group and an aralkyl group, and having the vapor pressure of at least 0.1 mmHg at 20.degree. C.
