    Abstract: The invention provides a novel room temperature-curable organopolysiloxane composition useful as an adhesive or a sealing material with remarkably extended workable time owing to the delayed surface filming. The base component in the composition is a conventional diorganopolysiloxane terminated with hydroxy groups at both molecular chain ends admixed with several known ingredients such as a cross linking agent, curing catalyst, filler and the like. The most characteristic ingredient in the composition effective to achieve the above mentioned desired property is a 1,1,1-trimethyl-3-hydrocarbyl-3,3-di(acylamino)disiloxane which belongs to a novel class of organopolysiloxane compounds and method is described for the preparation of these siloxane compounds.
