RTV Sealant Catalysts

TYTAN™ S range are titanium chelates used in the catalysis of neutral-cure RTV silicone sealants. They work by hydrolysing the methoxy groups which terminate oxime and alkoxy curing agents. Due to their moisture sensitivity they effectively scavenge trace moisture in the cartridge, giving the product an extended shelf life.

Sealants utilising TYTAN™ S catalysts have a rapid cure profile and excellent adhesion to many substrates. Extensive silanol cross-linking reduces deformation by increasing the elastic modulus. Organotitanates also have very favourable CLP labelling/no toxicity.


    • Catalyses the hydrolysis of methoxy terminated curing agents.

    • Cross-links silanol groups.

    • Moisture sensitive.

    • Able to cross-link with various chemical functionalities.


    • Extended shelf life through moisture scavenging.

    • Rapid cure profile.

    • Improved adhesion of the sealant to various substrates.

    • Increased modulus of elasticity for a lower deformation sealant.

    • Favourable toxicity profile.

    • Some grades show low colour development.

Typical Applications

    • Oxime cured RTV sealants.

    • Alkoxy cured RTV sealants.
