Used as a crosslinking agent in polymer chemistry, particularly in the production of thermosetting resins and coatings. Enhances heat resistance, chemical stability, and mechanical strength of polymers. Commonly applied in UV-curable systems such as inks, adhesives, and protective coatings due to its ability to participate in free radical polymerization. Also serves as a modifier in synthetic rubbers and elastomers to improve cure efficiency and network formation. Its trifunctional allyl groups enable efficient network building in silicone elastomers and radiation-cured materials.
