Description

Trimethoxytetradecylsilane is a high-purity organosilicon compound, specifically a long-chain alkyltrialkoxysilane. This chemical is a critical intermediate and surface modification agent valued for its ability to impart hydrophobic and organophilic properties to inorganic substrates. It is essential for manufacturers and formulators in the coatings, plastics, and advanced materials sectors seeking to enhance product performance through tailored surface chemistry.

Application

• Surface Modification Agent: Primarily used as a coupling agent to modify silica, glass, and other mineral fillers, improving their compatibility and dispersion in polymer matrices like plastics, rubbers, and sealants.
• Hydrophobic Coatings: A key precursor for formulating water-repellent and anti-corrosion coatings on metals, glass, and construction materials.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic surfaces in composite materials, adhesives, and primers.
• Nanomaterial Functionalization: Used to surface-treat nanoparticles (e.g., silica, titania) to control their aggregation and integrate them into advanced nanocomposites.
• Release Coatings: Employed in the production of silicone-based release liners for labels and tapes.
• Chromatography: Can serve as a derivatization agent or as a stationary phase modifier in chromatographic applications.

Quality Control

Our Trimethoxytetradecylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting purity, identity, and key physical properties are 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, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture.
