Description

4-[Tris(2-Methoxyethoxy)Silyl]Butyronitrile is a specialized organosilicon compound featuring a unique silyl ether and nitrile functional group architecture. This bifunctional structure makes it a valuable precursor and coupling agent in advanced material synthesis, offering controlled reactivity for surface modification and polymer cross-linking. It is essential for R&D and production in industries focused on creating high-performance silicones, adhesion promoters, and specialty polymers.

Application

• Silane Coupling Agent: Used to modify inorganic surfaces (glass, silica, metals) to improve adhesion with organic polymers and resins.
• Precursor for Functional Silicones: Serves as a key intermediate in the synthesis of custom silicone oils, elastomers, and resins with specific pendant groups.
• Adhesion Promoter in Coatings & Sealants: Enhances the bonding strength and durability of coatings, adhesives, and sealants on difficult-to-bond substrates.
• Surface Treatment for Fillers: Treats mineral fillers (e.g., silica, clay) to improve dispersion and compatibility within polymer matrices like rubbers and plastics.
• Cross-linking Agent: Utilized in the formulation of moisture-curable systems and polymer networks where controlled cross-link density is required.
• Research & Development: Employed in academic and industrial labs for developing novel hybrid organic-inorganic materials (ORMOSILs).

Quality Control

Our 4-[Tris(2-Methoxyethoxy)Silyl]Butyronitrile is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and high purity. Certificates of Analysis (COA) documenting all specifications are available upon request to support your quality assurance protocols.

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). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture absorption.
