摘要
<p>Alkoxy-functional one-component RTV silicone rubber composition which is self-stable and fast-curing. The composition is formed by reacting a silanol-terminated polysiloxane polymer with an alkoxy-functional cross-linking agent in the presence of a condensation catalyst. The present invention lies in the use of silicon-nitrogen compounds and silicon-nitrogen polymers as scavengers for unendcapped hydroxy groups in the above polyalkoxy-functional RTV systems. A preferred silicon-nitrogen compound is hexamethyldisilazane.</p>
