Description

10-Undecenyltrichlorosilane is a specialized organosilicon compound featuring a reactive trichlorosilyl head group and a terminal alkene (10-undecenyl) tail. This unique bifunctional structure makes it a critical coupling agent and surface modifier in advanced materials science. It is essential for industries requiring precise interfacial engineering to enhance adhesion, compatibility, and performance between dissimilar materials. Key users include manufacturers in the electronics, specialty polymers, and nanotechnology sectors.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals, creating a hydrophobic or reactive organic layer for improved bonding with polymers, resins, or coatings.
• Silane Coupling Agent: Enhances adhesion and mechanical properties in composite materials, including fiberglass-reinforced plastics, mineral-filled rubbers, and sealants.
• Precursor for Functional Silanes: Serves as a key intermediate for synthesizing other specialty silanes, where the terminal double bond can undergo further reactions like hydrosilylation or epoxidation.
• Nanomaterial Functionalization: Applied to modify nanoparticles (e.g., silica, quantum dots) to improve dispersion in organic matrices or to attach specific biomolecules for sensor applications.
• Adhesion Promoter in Electronics: Used in underfill materials, encapsulants, and dielectric layers to improve adhesion to silicon, glass, or metal substrates in microelectronic packaging.
• Hydrophobic Coating Formulation: A component in formulations for creating water-repellent, anti-corrosive coatings on various substrates.

Quality Control

Our 10-Undecenyltrichlorosilane is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. Our quality system supports compliance with relevant global chemical management regulations.

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 (e.g., nitrogen or argon) due to its hygroscopic and moisture-sensitive nature. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
