Used as a reactive diluent and crosslinking agent in epoxy resin systems, improving flexibility and adhesion in coatings, adhesives, and composite materials. Its ester functionality enhances compatibility with polymers and aids in modifying rheological properties. Commonly applied in specialty inks, electronic encapsulants, and fiber-reinforced plastics where low viscosity and good curing performance are required. Also serves as an intermediate in synthesizing functional monomers for UV-curable formulations.
