Description

Silane, (2,2-Dimethylpropoxy)ethenyldimethyl- is a specialized organosilicon compound characterized by its reactive vinyl and alkoxysilane functional groups. This unique bifunctional structure makes it a valuable coupling agent and surface modifier, bridging organic polymers with inorganic substrates. It is essential for manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries seeking to enhance material compatibility, adhesion, and durability.

Application

• As a coupling agent in mineral-filled polymer composites (e.g., glass fiber-reinforced plastics) to improve interfacial bonding and mechanical properties.
• As a surface treatment agent for glass, silica, and metal oxides to impart hydrophobic or organophilic characteristics.
• As a key monomer or crosslinking agent in the synthesis of silicone-modified polymers and hybrid organic-inorganic materials.
• In the formulation of high-performance adhesives and sealants to enhance adhesion to difficult substrates and environmental resistance.
• For the functionalization of nanoparticles to improve their dispersion and compatibility in various polymer matrices.
• In the production of release coatings and low-surface-energy materials.
• As a chemical intermediate in pharmaceutical and agrochemical research for introducing silane functionality.

Quality Control

Our production of Silane, (2,2-Dimethylpropoxy)ethenyldimethyl- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR analysis, to verify identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your technical requirements.

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 material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
