Description

Triethoxy-p-Tolylsilane 97 is a high-purity organosilicon compound, specifically a trialkoxysilane derivative with a tolyl functional group. This chemical serves as a critical coupling agent and surface modifier, enabling strong adhesion between organic polymers and inorganic substrates. It is essential for manufacturers in the advanced materials, coatings, and electronics industries seeking to enhance product performance, durability, and interfacial properties.

Application

• Silane Coupling Agent: Used to improve the bond strength and moisture resistance in fiberglass-reinforced plastics, mineral-filled composites, and tire cord adhesives.
• Surface Modification: Functionalizes silica, glass, metals, and other inorganic surfaces to impart hydrophobic or specific reactive properties.
• Adhesive & Sealant Formulations: Acts as an adhesion promoter in high-performance silicone, epoxy, and polyurethane systems.
• Resin & Polymer Synthesis: Employed as a monomer or cross-linking agent in the production of specialty silicones and hybrid organic-inorganic polymers.
• Electronics & Optics: Used in the fabrication of protective coatings, encapsulants, and low-k dielectric materials for semiconductor devices.
• Nanomaterial Functionalization: A key reagent for modifying nanoparticles to control dispersion and compatibility in various matrices.

Quality Control

Our Triethoxy-p-Tolylsilane 97 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency meet the specified standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

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); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation by moisture.
