Trimethylolpropane triglycidyl ether (TMPTGE) is an organic chemical in the glycidyl ether family. It has the formula C15H26O6 and the IUPAC name is 2-[2,2-bis(oxiran-2-ylmethoxymethyl)butoxymethyl]oxirane, and the CAS number 3454-29-3. It also has another CAS number of 30499-70-8 A key use is as a modifier for epoxy resins as a reactive diluent.

1,1,1-Trimethylolpropane triglycidyl ether




Manufacture


Trimethylolpropane and epichlorohydrin are reacted with a Lewis acid catalyst to form a halohydrin. The next step is dehydrochlorination with sodium hydroxide. This forms the triglycidyl ether.




Uses


As the molecule has 3 oxirane functionalities, a key use is modifying and reducing the viscosity of epoxy resins. These reactive diluent modified epoxy resins may then be further formulated into CASE applications: Coatings, Adhesives, Sealants, Elastomers. The use of the diluent does effect mechanical properties and microstructure of epoxy resins. It produces epoxy coatings with high impact resistance
Polymer systems with shape memory may also be produced with this particular molecule. Fluoropolymers have also been produced with the material via a photoinitiated mechanism. Production of biocompatible materials is also possible.
