Description

Tetra(2-Chloroethoxy)Silane is a versatile organosilicon compound characterized by its four reactive chloroethoxy functional groups. This structure makes it a valuable intermediate for introducing silicon-based linkages and modifying surface properties in advanced materials. It is particularly sought after by manufacturers in the specialty chemical, polymer, and electronics industries for applications requiring tailored silane coupling agents or precursors to functionalized siloxanes.

Application

• Silane Coupling Agent Precursor: Used to synthesize specialized silane coupling agents for enhancing adhesion between organic polymers and inorganic surfaces like glass, metals, or minerals.
• Surface Modification: Imparts specific functional groups to silica, nanoparticles, or other substrates to alter wettability, compatibility, or reactivity.
• Polymer & Resin Modification: Serves as a cross-linking agent or a monomer for producing modified silicones, epoxy resins, or other polymers with improved thermal or chemical resistance.
• Electronics & Semiconductor Materials: Employed in the formulation of dielectric coatings, encapsulants, or photoresists where specific silicon-organic hybrid properties are required.
• Specialty Chemical Synthesis: Acts as a key building block in organic synthesis for pharmaceuticals, agrochemicals, and liquid crystals.
• Hydrophobic Coatings: A component in formulations for creating water-repellent surfaces on textiles, construction materials, or optical devices.

Quality Control

Our Tetra(2-Chloroethoxy)Silane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications for purity and reactivity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and may react with strong acids and bases; keep the container tightly sealed under an inert atmosphere such as nitrogen or argon for long-term storage to prevent hydrolysis and maintain purity. Keep away from heat, sparks, and open flame.
