Used as a key intermediate in the synthesis of silicone polymers, particularly in the production of specialty siloxane copolymers. Its vinyl group enables hydrosilylation reactions, making it valuable in crosslinking processes for silicone rubbers and resins. Commonly applied in manufacturing heat-curable and UV-curable silicone coatings, where it enhances adhesion, flexibility, and thermal stability. Also utilized in surface modification of silica and glass to introduce organic functionality for improved compatibility in composite materials.
