Room temperature-vulcanized two-component

As shown in Scheme 8, condensation can take place by the reaction of terminal OH groups of poly(dimethylsiloxane) with tri-21 or tetraalkoxy-22 silane monomers or with polyalkoxysilanes in the presence of a catalyst such as dibutyltin dilaurate or tin octanoate, which are colorless and pourable. The products from these reactions are white or beige, room temperature-vulcanized two-component system (RTV-2) silicone rubbers. Polyalkoxy silane undergoes similar reaction with poly(dimethylsiloxane) to give RTV-2 silicone rubber. The reaction is isothermal and a volatile alcohol forms from the corresponding alkoxy groups. [Pg.167]
