Used as a crosslinking agent in polymer synthesis, particularly in the production of specialty resins and coatings. Its dual alkyne functionality allows for efficient UV- or heat-induced curing, making it valuable in advanced lithography and electronic encapsulation materials. Also employed in the formulation of reactive diluents to reduce viscosity in radiation-curable systems without compromising performance. Shows promise in 3D printing resins due to rapid curing and low shrinkage properties.
