Abstract
A moisture curable solventless organopolysiloxane composition is provided useful as an adherent construction sealant. Improved cure rate, higher elongation at break values and lower modulus RTVs are achieved by using a bis(ureido)silane as a coupler and an aminoxysiloxane as a crosslinker for a silanol-terminated polydiorganosiloxane base polymer.
