Description

Diethoxymethyl[(1-Methylvinyl)Oxy]Silane is a specialized organosilicon compound, specifically a vinyl-functional alkoxysilane. This chemical is valued for its dual reactivity, featuring both hydrolyzable ethoxy groups and a polymerizable vinyl group, making it a versatile coupling agent and monomer. It is primarily used in the formulation of advanced silicone polymers, adhesives, and coatings where enhanced adhesion to inorganic substrates and cross-linking capabilities are required. Industries such as specialty chemicals, advanced materials, and electronics rely on this silane for developing high-performance products.

Application

• As a coupling agent in mineral-filled composites (e.g., glass, silica) to improve interfacial adhesion and mechanical properties.
• A key cross-linking monomer in the synthesis of silicone resins and modified silicone polymers.
• Used in the formulation of adhesives and sealants to enhance bonding to glass, metal, and ceramic surfaces.
• As a surface treatment agent for fillers and pigments to improve dispersion and compatibility in polymer matrices.
• Employed in the production of moisture-curable coatings and inks for durable, weather-resistant finishes.
• A precursor in sol-gel chemistry for creating hybrid organic-inorganic materials with tailored properties.
• Potential use as an adhesion promoter in electronic encapsulants and underfill materials.

Quality Control

Our Diethoxymethyl[(1-Methylvinyl)Oxy]Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards typical for organosilicon intermediates. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters 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 a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation upon contact with atmospheric moisture.
