Description

10-Undecenylsilane is a specialized organosilicon compound featuring a terminal alkene group, making it a versatile bifunctional reagent for surface modification and polymer chemistry. Its unique structure allows it to act as a coupling agent, bridging organic polymers with inorganic substrates to enhance adhesion, dispersion, and material performance. This product is essential for R&D and production in the advanced materials, coatings, and specialty chemical sectors seeking to engineer specific surface properties and create hybrid materials.

Application

• Surface Modification Agent: Used to functionalize glass, silica, metals, and other inorganic surfaces to introduce hydrophobic or reactive vinyl groups.
• Coupling Agent for Composites: Improves the interfacial adhesion between organic polymer matrices (e.g., polyolefins, epoxies) and inorganic fillers like glass fibers or minerals.
• Silicone Chemistry Intermediate: Serves as a key building block in the synthesis of custom silicone oils, resins, and elastomers with pendant reactive sites.
• Adhesion Promoter in Coatings: Incorporated into primers and coating formulations to enhance bond strength to difficult substrates.
• Nanomaterial Functionalization: Applied to modify nanoparticles (e.g., silica, titania) for better dispersion and compatibility in nanocomposites.
• Research & Development: A valuable tool in academic and industrial labs for developing novel hybrid organic-inorganic materials and studying surface science.

Quality Control

Our 10-Undecenylsilane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC or NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with every shipment to guarantee it meets your precise technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
