Octyltriethoxysilane Application
Octyltriethoxysilane is also useful as a surface modifier for nanoparticles and fillers, where it improves the compatibility between the materials and enhances their dispersion. The compound is often used in the production of high-performance composites, where it enhances interfacial bonding and reduces the degradation of the composite material.
In the textile industry, octyltriethoxysilane is used as a fabric softener and as a treatment for water repellency and stain resistance, which can help prolong the life of the fabric and reduce the need for frequent washing.
It is also used as a surface treatment in the manufacturing of electronic materials, such as semiconductors, to improve their hydrophobicity and adhesion to other surfaces.
