[3] A key use is acting as a modifier for epoxy resins as a reactive diluent that adds flexibility and improved mechanical properties.

This process is followed neutralizing the catalyst with a small amount of sodium hydroxide and then adding a large excess of epichlorohydrin as solvent.

To re-form the epoxide rings in a dehydrochlorination reaction, solid sodium hydroxide flake is used rather than a solution.

A 2018 study concluded that its use as a flexiblizing agent as well as an epoxy diluent has application in the aviation field.

[9][10] These reactive diluent modified epoxy resins may then be further formulated into CASE applications: coatings,[11] adhesives,[12] sealants,[13] elastomers.
