Description

Tetradecyltriethoxysilane is a long-chain alkyltrialkoxysilane coupling agent, a key organosilicon compound for modifying inorganic surfaces. Its primary value lies in imparting durable hydrophobic and oleophilic properties to materials, enhancing compatibility and performance in composite systems. This silane is essential for manufacturers in the coatings, plastics, and specialty chemical industries seeking to improve adhesion, dispersion, and moisture resistance.

Application

• Surface Modification Agent: Imparts water repellency (hydrophobicity) to glass, silica, and other mineral fillers used in polymer composites.
• Coupling Agent for Composites: Enhances the interfacial adhesion and dispersion of inorganic fillers in polyolefin (e.g., PP, PE) and other polymer matrices, improving mechanical properties.
• Waterproofing Additive: Used in construction chemicals, sealants, and coatings to provide long-lasting water resistance.
• Filler Treatment: Pre-treatment for precipitated silica, calcium carbonate, and talc to reduce moisture absorption and improve processing in rubber and plastic compounds.
• Release Coatings: Serves as a precursor for creating low-surface-energy, easy-release coatings on various substrates.
• Adhesion Promoter: Improves the bonding of resins and paints to metallic or mineral surfaces in challenging environments.

Quality Control

Our Tetradecyltriethoxysilane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment to guarantee consistency and traceability for our industrial partners.

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); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity.
