Room temperature curable polysiloxane compositions

摘要

A room temperature curable polysiloxane composition comprises the use of acyloxy groups as functional groups instead of the conventional OH groups. Alkoxysilanes can be used as silane crosslinking agents, the polysiloxane composition is quickly cured under the effect of atmospheric moisture without the necessity of special requirements to be met by the crosslinking catalyst. An Independent claim is included for a process for the preparation of the polysiloxane composition involving reaction of OH group containing polysiloxane with acyloxy group containing silanes with subsequent or simultaneous mixing in of an alkoxysilane crosslinking agent.
