MOISTURE-CURABLE COMPOSITIONS CONTAINING AMINOALKOXY-FUNCTIONAL SILICONE ABSTRACT A moisture-curable silicone composition, suitable for use as a coating or pressure-sensitive adhesive, is disclosed, said composition comprising (i) a hydroxyl- functional organopolysiloxane resin comprising R3SiO1/2 siloxane units and SiO4/2 siloxane units in a molar ratio of 0.5/1 to 1.2/1, respectively, wherein R is a hydrocarbon or halogenated hydrocarbon radical; (ii) a diorganopolysiloxane polymer having at least two silicon-bonded alkoxy groups and at least one carbon-bonded amine group in its molecule, said polymer having a viscosity at 25°C. of 20 to 100,000 mPa?s (centipoise), the weight ratio of said resin to said polymer being in the range 20:80 to 80:20; (iii) optionally, a hydrolyzable silane in sufficient amount to provide stability to said composition; and (iv) optionally, sufficient catalyst to accelerate the cure of said composition.
