Description

7-Octenyltrichlorosilane is a versatile organosilicon compound featuring a reactive trichlorosilyl head group and a terminal alkene (octenyl) tail. This unique bifunctional structure makes it a critical coupling agent and surface modifier, enabling strong covalent bonds between inorganic substrates and organic polymers. It is essential for manufacturers in the advanced materials, electronics, and specialty chemical sectors seeking to enhance adhesion, hydrophobicity, and compatibility in composite systems.

Application

• Surface Modification Agent: Primarily used to functionalize glass, silica, metals, and other inorganic surfaces, creating a hydrophobic, organophilic monolayer for improved polymer adhesion.
• Coupling Agent for Composites: Enhances the interfacial bonding between mineral fillers (e.g., silica, clay) and organic polymer matrices in plastics, rubbers, and resins, improving mechanical properties.
• Adhesion Promoter in Coatings & Sealants: Incorporated into primers and formulations to dramatically improve the adhesion of paints, inks, and sealants to difficult substrates like glass and aluminum.
• Intermediate for Specialty Silicones: Serves as a key building block in the synthesis of custom silicone oils, fluids, and cross-linkers with specific alkene functionality for further reactions.
• Nanomaterial Functionalization: Used to modify nanoparticles (SiO2, TiO2) to prevent aggregation and facilitate their dispersion in non-polar solvents and polymer hosts.
• Chromatography Stationary Phases: Employed to derivatize silica gel for the preparation of reversed-phase HPLC columns with specific selectivity.

Quality Control

Our 7-Octenyltrichlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C under an inert atmosphere (argon or nitrogen). Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed and handled under dry conditions to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
