n-Propyltrimethoxysilane: Guide
n-Propyltrimethoxysilane is a colorless or light yellow transparent liquid used in fine chemical technology. It is produced through a process involving 3-aminopropyltrimethoxysilane, offering enhanced coupling activity and stability.
By prehydrolyzing 3-aminopropyltriethoxysilane under specific conditions, most of the ethoxy groups are converted to silanol (SiOH), preventing premature cross-linking in aqueous systems. This results in a product with strong coupling activity, excellent storage stability, and low ethanol content, making it suitable for direct application in water-based systems.
Applications include glass fiber reinforcement, waterborne polyurethane modification, waterborne coatings viscosity control, and other waterborne systems, improving performance and stability in various industries.
