Description

n-Decyltrichlorosilane is a high-purity organosilicon compound widely used as a key intermediate in organic synthesis and surface modification. Its primary value lies in its ability to act as a versatile coupling agent, forming durable covalent bonds with inorganic substrates to impart hydrophobic and oleophobic properties. This makes it essential for manufacturers in the semiconductor, nanotechnology, and specialty coatings industries seeking to enhance material performance and stability.

Application

• Surface Modification Agent: Used to create hydrophobic monolayers on glass, silicon, and metal oxide surfaces for water-repellent coatings.
• Silane Coupling Agent: Acts as an intermediary to improve adhesion between organic polymers and inorganic materials in composite manufacturing.
• Chemical Intermediate: Serves as a critical precursor in the synthesis of more complex functionalized silanes and silicone polymers.
• Semiconductor Manufacturing: Employed in the passivation of surfaces and as a reagent in chemical vapor deposition (CVD) processes.
• Nanoparticle Functionalization: Used to modify the surface of silica and other nanoparticles to control dispersion and reactivity.
• Waterproofing Treatments: Applied in formulations for textiles, construction materials, and electronic components.

Quality Control

Our n-Decyltrichlorosilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
