Used primarily as a reactive diluent and modifier in epoxy resin systems, enhancing flexibility and adhesion in coatings, adhesives, and composite materials. Its unsaturated chain allows for further chemical modification or crosslinking, making it valuable in developing specialty polymers with improved toughness and thermal stability. Commonly applied in high-performance industrial coatings, electrical encapsulation, and UV-curable formulations due to its ability to reduce viscosity while maintaining reactivity.
