Cas no 160877-25-8 (2-butyl-triethoxysilane)

2-Butyl-triethoxysilane is an organosilane compound characterized by its triethoxy functional group and a butyl chain. This silane is commonly used as a coupling agent, surface modifier, or adhesion promoter in various industrial applications, including coatings, adhesives, and sealants. Its hydrolyzable ethoxy groups enable covalent bonding with inorganic substrates, such as glass, metals, or minerals, while the hydrophobic butyl group enhances compatibility with organic matrices. The compound improves interfacial adhesion, moisture resistance, and durability in composite materials. Its stability under processing conditions and reactivity with hydroxylated surfaces make it suitable for enhancing performance in polymer and filler systems. Proper handling requires consideration of its moisture sensitivity.
