Organometallic Catalysts

A picture of a running track with a sunset

Product Overview

 

TIB's range of organometallic catalysts are primarily based on 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-modified 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.
