Description

(2-Ethylbutoxy)(Trimethyl)Silane CAS NO 17888-61-8 is a specialized organosilicon compound used as a versatile chemical intermediate and surface modifying agent. Its value lies in its ability to introduce hydrophobic, organic-functional silane groups to inorganic substrates or polymer matrices, enhancing material compatibility and performance. This product is essential for manufacturers in the silicone polymer, advanced coatings, and specialty chemical synthesis sectors seeking to tailor material properties.

Application

• Silicone Polymer Modification: Acts as a chain terminator or functional monomer in the synthesis of modified polysiloxanes, influencing viscosity, reactivity, and end-group characteristics.
• Surface Treatment Agent: Used to hydrophobize and functionalize the surface of silica, glass, and other metal oxides to improve dispersion in organic polymers and resins.
• Adhesion Promoter: Enhances the bond between organic coatings or adhesives and inorganic substrates in composite material manufacturing.
• Chemical Synthesis Intermediate: Serves as a protected silanol precursor or a reagent for introducing the (2-ethylbutoxy)silane moiety into more complex molecular architectures.
• Water Repellency Treatments: Formulated into coatings and sealants for construction materials to impart moisture resistance.
• Lubricant & Release Agent Component: Incorporated into formulations where low surface energy and thermal stability are required.
