Room temperature vulcanizing (RTV) elastic silicone usually employs organic tin compounds as a hardener. It is well known that they are strong biohazardous. Thus, European Union is going to regulate the use of organic tin compounds and to exclude them from industrial products till 2015. Authors have succeeded in making a substitute of organic tin compounds as a hardener for RTV elastic silicone by using titanium alkoxide and a carboxylate ester as a hardener and a promoter, respectively. In this paper, composites of RTV elastic silicone made with silica particles and a silane coupling agent are studied based on the mechanical, heat-resistive and adhesive properties.
