Product Code：SP8015
Product Name：N-OCTYLTRIETHOXYSILANE
Product Introduction：
N-Octyltriethoxysilane is a long-chain alkyl silane containing a hydrophobic C8 chain and three hydrolyzable ethoxy groups. It forms durable, water-repellent monolayers on inorganic surfaces such as glass, metals, and ceramics. It is widely used as a surface modifier, hydrophobing agent, and dispersant for fillers in coatings, sealants, and construction materials.
