Abstract
This composition comprises (A) a diorganopolysiloxane terminated with hydroxyl groups at both ends of its molecular chain having a viscosity of 25 to 1,000,000 cSt at 25.degree. C., (B) a low molecular weight organosilane or straight chain organosiloxane having silanol groups, such as HO(Me.sub.2 SiO)H, Me.sub.3 SiO[Me(OH)SiO].sub.2 SiMe.sub.3 or mixtures thereof, (C) a hydrolyzable silane, and (D) a silica filler having a specific surface area of 50 m.sup.2 /g or more. The composition has good non-flowability and exhibits good application workability when surface-finishing with spatula, and therefore is useful as building sealing materials.
