Used extensively in silicone-based formulations due to their reactive vinyl groups, enabling crosslinking in RTV (room temperature vulcanizing) and HTV (high temperature vulcanizing) silicone rubbers. Commonly employed in sealants, adhesives, and encapsulants for electronics, where flexibility, thermal stability, and moisture resistance are critical. Also utilized in coatings, mold-making, and as a base in medical-grade silicones owing to biocompatibility and durability. The terminal vinyl functionality allows for precise curing when combined with hydride-functional siloxanes in the presence of platinum catalysts, making them ideal for addition-cure systems.
