Used as a reactive intermediate in the synthesis of silicone-based polymers, enhancing thermal stability and flexibility in coatings and elastomers. Commonly employed in the formulation of specialty adhesives and sealants where improved water repellency and adhesion to difficult substrates are required. Also serves as a building block in the development of siloxane networks for low-surface-energy materials used in release coatings and surface modifiers. Its phenyl and methyl groups contribute to better oxidative stability and performance at elevated temperatures compared to purely alkyl-substituted siloxanes.
