Description

Triethoxy(2-Phenylpropyl)Silane is a specialized organosilicon compound, a phenylalkyl-substituted triethoxysilane, that serves as a versatile coupling agent and surface modifier. Its molecular structure, featuring both a hydrophobic phenylpropyl group and hydrolyzable ethoxy groups, makes it a critical intermediate for enhancing adhesion, compatibility, and performance in composite materials. This product is essential for manufacturers in the advanced materials, coatings, and sealants industries seeking to improve the interface between organic polymers and inorganic substrates. Its unique properties enable tailored surface characteristics and durable material integration.

Application

• As a coupling agent in mineral-filled composites (e.g., glass fiber, silica) to improve mechanical strength and moisture resistance.
• As a surface treatment agent for nanoparticles and fillers to enhance dispersion and compatibility in polymer matrices.
• As a key monomer or intermediate in the synthesis of specialized silicone resins and hybrid organic-inorganic polymers.
• In the formulation of high-performance adhesives and sealants to promote adhesion to challenging substrates like metals and glass.
• For modifying the surface properties of coatings to impart hydrophobicity, corrosion resistance, or improved weatherability.
• In research and development for creating novel silylating agents used in organic synthesis and material science.

Quality Control

Our Triethoxy(2-Phenylpropyl)Silane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC, NMR, and purity assays, to ensure it meets precise specifications and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and key physical properties is provided with every shipment to guarantee traceability and compliance with your quality 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/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
