- Titanium-based catalysts which are also widely used, show however two major drawbacks: they have slower kinetics than tin-based catalysts; and in the case of the preparation of one-component neutral silicone compositions (where R ° is an alkyl or imino residue), elastomers are obtained which allow a tacky surface feel several hours after having a skin and during this time they remain sensitive to the taking dust for example. It should be added to this that sealants catalyzed by tin frequently exhibit, in particular when they give off alcohol, stability problems, which is generally not the case when the catalyst is a titanium-based compound. .
