Description

n-Decyldimethylmethoxysilane is a high-purity organosilicon compound, specifically a long-chain alkyl alkoxysilane. This chemical is a crucial intermediate and surface-modifying agent valued for its ability to impart hydrophobic properties and improve compatibility between organic and inorganic materials. It is essential for manufacturers in the silicone polymer, advanced materials, and coatings industries seeking to enhance product performance and durability.

Application

• Silicone Intermediate: A key monomer or cross-linking agent in the synthesis of specialty silicone oils, resins, and elastomers.
• Surface Modification: Used as a coupling agent to hydrophobically treat inorganic fillers (e.g., silica, minerals) for improved dispersion in polymer matrices.
• Water Repellents: Formulated into coatings and sealants for construction materials, textiles, and paper to provide durable water resistance.
• Adhesion Promotion: Enhances the bond between organic polymers and inorganic substrates like glass, metals, and minerals in composite materials.
• Release Agents: Serves as a component in mold release formulations for plastics and rubber manufacturing.
• Pharmaceutical & Cosmetic Ingredients: Potential use as a conditioning agent or intermediate in personal care products, subject to appropriate purity grades.

Quality Control

Our n-Decyldimethylmethoxysilane is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure it meets precise specifications for purity, identity, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and 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); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and degradation.
