AP-Silane 98
Advanced Polymer · AP-Silane
AP-Silane 98 is a high-purity n-octyltriethoxysilane developed for hydrophobizing inorganic surfaces such as concrete, stone, glass, and metals. It penetrates porous substrates and chemically reacts to deliver long-lasting water repellency without altering the surface’s natural appearance. Typically diluted in alcohols, mineral spirits, or PDMS, AP-Silane 98 can be applied by brush, roller, or spray, providing versatile and durable protection across architectural and industrial applications.
