Description

Butoxydiethoxymethylsilane is a versatile organosilicon compound, specifically an alkoxysilane, known for its role as a key coupling agent and surface modifier. Its value lies in its ability to form stable bonds between organic polymers and inorganic materials, enhancing adhesion, dispersion, and water repellency. This makes it an essential intermediate for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of advanced composites and specialty chemicals.

Application

• As a coupling agent in mineral-filled composites (e.g., fiberglass, minerals in plastics) to improve mechanical properties and moisture resistance.
• As a surface treatment agent for pigments, fillers, and glass fibers to enhance dispersion in polymer matrices and increase interfacial adhesion.
• As a key intermediate in the synthesis of more complex silane-based specialty chemicals and functional polymers.
• In the formulation of water-repellent coatings and sealants for construction and automotive applications.
• As an adhesion promoter in high-performance adhesives and sealants, particularly for bonding dissimilar materials.
• In the production of silicone resins and modifiers for tailored material properties.

Quality Control

Our Butoxydiethoxymethylsilane is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay and impurity profile determination via GC or HPLC, to ensure it meets precise specifications and consistent performance for industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment.

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 a dry inert atmosphere (e.g., nitrogen) to prevent degradation by atmospheric moisture.
