<p>Novel filled curable compositions comprise a mixture and or a reaction product of hydroxypolyorganosiloxane, an organic polymer having oxyalkylene units in its molecular chain and at least two reactive groups - SiR(3-b)Xb in which R represents a divalent hydrocarbon group, X represents an alkoxy, alkenyloxy or oximo group and (b) has the value 0, 1 or 2. The compositions may be used as moisture curable sealants which are to provide an elastomeric seal having improved paintability.</p> |
