Its main use is in modifying epoxy resins especially viscosity reduction whilst flexibilizing.

This process is followed by washing with sodium hydroxide to re-form the epoxide rings in a dehydrochlorination reaction.

The chain length helps give some degree of flexibility as an epoxy resin has rigid aromatic rings which are planar.

[6] These systems may then be formulated into CASE applications: Coatings,[7] Adhesives, Sealants, Elastomers, and composite materials.

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