Allyl Octadecyl Methylsilane is widely used in the formulation of surface-modifying agents due to its ability to impart hydrophobic properties to materials. It is commonly applied in coatings and paints to enhance water repellency and improve durability. Additionally, it is utilized in the production of adhesives and sealants to increase their resistance to moisture and environmental degradation. In the textile industry, it serves as a finishing agent to create water-resistant fabrics. The compound is also employed in the modification of fillers and additives in polymer composites, enhancing their compatibility and performance in various industrial applications.
