Description

2-Butanone o-(Diethoxymethylsilyl)Oxime is a specialized organosilicon compound that serves as a versatile coupling agent and surface modifier. Its unique structure, featuring both a silyl ether and an oxime functional group, makes it a valuable intermediate for enhancing adhesion and compatibility in advanced material systems. This chemical is primarily sought by manufacturers in the silicone polymer, adhesive, and coatings industries for its ability to improve the performance and durability of composite materials.

Application

• As a silane coupling agent to improve the bond between inorganic fillers (e.g., glass, minerals) and organic polymer matrices in composites.
• As a surface treatment agent for glass fibers, silica, and other minerals to enhance their dispersion and interfacial adhesion in plastics and rubbers.
• As a key intermediate in the synthesis of more complex silicone-based materials and functional polymers.
• In the formulation of specialty adhesives and sealants to promote adhesion to difficult-to-bond substrates.
• For the modification of resin systems, including epoxies and polyurethanes, to tailor mechanical properties and moisture resistance.
• In research and development for creating novel hybrid organic-inorganic materials.

Quality Control

Our production of 2-Butanone o-(Diethoxymethylsilyl)Oxime adheres to a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, purity, and absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent degradation from atmospheric moisture.
