[dubious – discuss][1] A key use is as a modifier for epoxy resins as a reactive diluent.

[2][3] [4] Trimethylolethane and epichlorohydrin are reacted with a Lewis acid catalyst to form a halohydrin.

[5][6] As the molecule has 3 oxirane functionalities, a key use is modifying and reducing the viscosity of epoxy resins but giving higher functionality.

[7] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: Coatings, Adhesives, Sealants, and Elastomers.

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