Description

10-(Carbomethoxy)Decyldimethylmethoxysilane is a specialized organosilicon compound featuring a long alkyl chain terminated with a carbomethoxy group and a hydrolysable methoxysilane moiety. This unique bifunctional structure makes it an essential coupling agent and surface modifier, enabling strong covalent bonds between organic polymers and inorganic substrates. It is primarily used by manufacturers in the advanced materials, coatings, and adhesives industries seeking to enhance composite material performance, improve adhesion, and tailor surface properties.

Application

• Surface Modification Agent: Used to functionalize the surface of inorganic fillers (e.g., silica, glass, metals) to improve compatibility and dispersion in polymer matrices.
• Coupling Agent for Composites: Enhances the interfacial adhesion between organic resins (epoxy, polyurethane) and inorganic reinforcements in fiberglass, mineral-filled plastics, and nanocomposites.
• Adhesion Promoter in Coatings & Sealants: Incorporated into primers and formulations to dramatically improve coating adhesion to difficult substrates like metals, glass, and plastics.
• Crosslinking Agent: Serves as a reactive intermediate in the synthesis of silicone-based polymers and hybrid organic-inorganic networks (ORMOSILs).
• Hydrophobic Coating Precursor: Used to create water-repellent and anti-corrosive surface treatments on various materials.
• Chemical Anchoring in Biomedical Materials: Facilitates the stable immobilization of bioactive molecules or polymers onto medical device surfaces and diagnostic platforms.

Quality Control

Our production of 10-(Carbomethoxy)Decyldimethylmethoxysilane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and purity verification, to ensure consistency and meet precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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/59-77°F). Due to its moisture-sensitive (hygroscopic) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
