Description

2-Cyanoethylmethyldiethoxysilane is a versatile organosilicon compound featuring both cyanoethyl and alkoxysilyl functional groups. This dual functionality makes it a valuable coupling agent and surface modifier, enabling strong adhesion between organic polymers and inorganic substrates. It is primarily used by manufacturers in the silicone rubber, adhesive, sealant, and electronics industries to enhance material performance and durability.

Application

• As a key adhesion promoter and coupling agent in silicone sealants and RTV (Room-Temperature-Vulcanizing) rubbers.
• Surface treatment of fillers like silica and glass fibers to improve dispersion and reinforcement in polymer composites.
• Modification of mineral surfaces to increase hydrophobicity and compatibility with organic resins.
• Intermediate in the synthesis of more complex functional silanes for specialized applications.
• Used in electronic encapsulants and potting compounds to improve moisture resistance and adhesion.
• Potential crosslinking agent or chain extender in the production of specialty silicone polymers.

Quality Control

Our 2-Cyanoethylmethyldiethoxysilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and identity confirmation via FTIR (Fourier-Transform Infrared Spectroscopy), to ensure it meets precise specifications for industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and degradation.
