Organometallic Catalysts

TIB's range of organometallic catalysts are primarily based around tin, bismuth, zinc and aluminium chemistry although there are other products available. These catalysts are widely used in the catalysis of polyurethanes, silane-terminated polymers (STP)/silane-modifed polymers(SMP), esterification/transesterification, amidisation and in the synthesis of alkyd and polyester resins. Typical application areas in the CASE industry sector i.e. coatings, adhesives, sealants and elastomers. Industrial organic synthesis is the other primary use case.


    • Organometallic catalysts based on tin, bismuth, zinc, aluminium, zirconium, copper, cerium, titanium, potassium and iron.

    • Inorganic catalysts based primarily on tin and bismuth.

    • Sulfonic acid catalysts also available.

    • High purity. Different physical forms available for some grades.

    • No use of conflict minerals.


    • Selective catalysis possible with minimal side products. Very active or delayed reaction possible.

    • Low temperature or high temperature activation (latent) possible.

    • Toxicologically inert grades available.

    • Non-tin based catalysts available where use of tin is an issue.

    • Low discolouration of the finished system possible.

Typical Applications

    • Oleochemistry - esterification and transesterification.

    • Catalysis of polyurethane-based coatings, adhesives and sealants.

    • Cross-linking of silane-modified polymers, particularly popular in new generation sealants.

    • Catalysis of PVC and thermoplastics, in particular XLPE.

    • Synthesis of alkyd resins, polyesters and unsaturated polyesters.

Featured grades with technical datasheets

A brief overview of the key grades is given below. You will find the Technical Datasheets (TDS) available for download. If you are looking for a Safety Datasheet (SDS) or Product Safety Information (PSI) then please get in touch by phone or via the contact buttons at the top of the page.

Should you not find what you are looking for here then please note that we have further grades available besides these. One of our Technical Sales team will be happy to help. All of the sales team are technically qualified and will be able to advise you on which product to choose. You can either call us, email us or fill in a quick form at the top of the page to get us to call you (Request a Callback).
