Description

Docosyltrichlorosilane is a high-purity organosilicon compound, specifically a long-chain alkyltrichlorosilane, serving as a critical intermediate in advanced material synthesis. Its primary value lies in its ability to form durable, hydrophobic, and self-assembled monolayers on various substrates, enabling precise surface modification. This product is essential for manufacturers and R&D facilities in the specialty chemicals, nanotechnology, and advanced coatings industries seeking to engineer surfaces with specific functional properties.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, silicon wafers, metals, and polymers for anti-fouling, anti-corrosion, and easy-clean applications.
• Nanomaterial Synthesis: Acts as a functionalization agent for nanoparticles (e.g., silica, quantum dots) and carbon nanotubes to improve dispersion and compatibility in polymer matrices.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic surfaces in composite materials and specialty adhesives.
• Release Coating Intermediate: Employed in the formulation of silicone-based release liners for pressure-sensitive adhesives and industrial molding processes.
• Chemical Vapor Deposition (CVD) Precursor: Used in the deposition of thin silicon-containing films for microelectronics and optical devices.
• Research & Development: A key reagent in academic and industrial labs for studying self-assembled monolayers (SAMs) and surface chemistry.

Quality Control

Our Docosyltrichlorosilane is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is 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. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
