Description

Bis(3-Cyanopropyl)Dimethoxysilane is a versatile organosilicon compound featuring both cyano and methoxysilane functional groups. This bifunctional nature makes it a valuable coupling agent and intermediate for synthesizing advanced materials with tailored surface properties. It is primarily utilized in the production of specialty polymers, adhesives, and surface modification agents for fillers and reinforcements. Industries such as advanced composites, electronics, and specialty coatings rely on this silane for its ability to enhance compatibility and adhesion between organic and inorganic phases.

Application

• As a coupling agent for glass fibers, minerals, and inorganic fillers in polymer composites.
• As a key intermediate in the synthesis of silicone polymers and resins with specific functional properties.
• For the surface modification of nanoparticles (e.g., silica, alumina) to improve dispersion in organic matrices.
• In the formulation of adhesives and sealants to promote bonding to various substrates.
• As a crosslinking agent or chain extender in specialty polymer synthesis.
• In the development of release coatings and non-stick surfaces.
• For research and development of novel hybrid organic-inorganic materials (ORMOSILs).

Quality Control

Our Bis(3-Cyanopropyl)Dimethoxysilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identity confirmation by FT-IR, to ensure it meets high-purity standards suitable for industrial and R&D applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from strong acids, bases, and oxidizing agents.
