Description

Trimethoxy-Phenyl-Silane is a versatile organosilicon compound that serves as a critical coupling agent and surface modifier. Its unique structure, featuring both hydrolyzable methoxy groups and a stable phenyl ring, enables it to bridge organic and inorganic materials, enhancing adhesion, dispersion, and compatibility. This product is essential for manufacturers in the advanced materials, coatings, and electronics industries seeking to improve the performance and durability of their composite systems.

Application

• Silane Coupling Agent: Used to promote adhesion between inorganic fillers (like glass, minerals) and organic polymer matrices in composites, sealants, and adhesives.
• Surface Treatment for Fillers: Modifies the surface of silica, alumina, and other minerals to improve dispersion in plastics, rubbers, and coatings, reducing viscosity and enhancing mechanical properties.
• Precursor for Silicone Resins & Polymers: Acts as a key monomer or cross-linking agent in the synthesis of phenyl-containing silicone resins, which offer high thermal stability and optical clarity.
• Water Repellent & Protective Coatings: Forms hydrophobic films on surfaces such as concrete, stone, and glass, providing water repellency and protection against weathering.
• Electronics & Semiconductor Industry: Employed as an adhesion promoter in photoresists, dielectric layers, and as a surface primer in microelectronic packaging.
• Intermediate for Specialty Chemicals: Serves as a valuable building block for synthesizing more complex organosilane derivatives with tailored functionalities.

Quality Control

Our Trimethoxy-Phenyl-Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and FTIR spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with every shipment to guarantee 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); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and reduced efficacy.
