[4][5] It also has another CAS number of 30499-70-8[6][7] A key use is as a modifier for epoxy resins as a reactive diluent.

[8] Trimethylolpropane and epichlorohydrin are reacted with a Lewis acid catalyst to form a halohydrin.

[9][10] As the molecule has 3 oxirane functionalities, a key use is modifying and reducing the viscosity of epoxy resins.

[11] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: Coatings,[12] Adhesives,[13] Sealants,[14] Elastomers.

The use of the diluent does effect mechanical properties and microstructure of epoxy resins.
