Abstract
Single-component diorganopolysiloxane compositions which are storage-stable in the absence of atmospheric moisture and which crosslink into silicone elastomeric state in the presence of moisture, are comprised of an alkoxy-terminated diorganopolysiloxane, a functionalization catalyst containing a primary or secondary amine group, a tin condensation catalyst, a filler material, and an effective stabilizing amount of an alkyl or aryl isocyanate-substituted diorganopolysiloxane.
