Description

Silane, (4-Ethenylphenyl)Diethoxymethyl- is a specialized organosilicon compound featuring both a vinylbenzyl group and hydrolyzable ethoxy functionalities. This dual reactivity makes it a highly effective coupling agent and surface modifier, crucial for enhancing the adhesion between organic polymers and inorganic substrates. It is primarily utilized by manufacturers in the advanced composites, coatings, and electronics industries seeking to improve material performance and durability. Our supply ensures consistent high purity and reliable performance for your critical formulation needs.

Application

• Surface Modification Agent: Used to treat glass, silica, and metal oxides to improve the bonding of resins and polymers in composite materials.
• Adhesion Promoter: Enhances the adhesion of coatings, inks, and adhesives to difficult-to-bond substrates like metals and glass.
• Crosslinking Agent: Functions as a reactive monomer or crosslinker in the synthesis of silicone-modified polymers and resins.
• Filler Treatment: Treats mineral fillers (e.g., silica, clay) in rubber and plastic compounds to improve dispersion and mechanical properties.
• Electronic Materials: Employed as a precursor in the fabrication of dielectric layers and protective coatings in microelectronics.
• Fiber Sizing: Applied as a key component in sizing formulations for glass and carbon fibers to optimize the fiber-matrix interface.

Quality Control

Every batch of (4-Ethenylphenyl)Diethoxymethyl- Silane is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards and provide comprehensive analytical data. A Certificate of Analysis (COA) detailing purity, identity, and key specifications is available for each shipment upon request, guaranteeing traceability and consistency for your production processes.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
