Abstract: There is provided a two-part moisture cure organopolysiloxane composition comprising a base part and a catalyst package part. The catalyst package part, despite comprising amino silane(s), alkoxy silane(s), tin catalyst(s) and optionally reinforcing filler(s) and/or extending filler(s) in a carrier fluid, undergoes minimal phase separation during storage. This is achieved by utilizing one or more polyarylorganosiloxane polymers or silicone copolymers thereof as the carrier fluid, enabling the catalyst package part to be stored and function as a shelf stable continuous phase.
