Description

N'-[3-(Trimethoxysilyl)Propyl]-n-[(Vinylphenyl)Methyl]Ethylenediamine is a specialized organosilane coupling agent featuring both a primary amine and a vinylbenzyl group, offering dual reactivity for advanced material synthesis. This compound is engineered to create robust covalent bonds between inorganic substrates and organic polymers, significantly enhancing composite material performance. It is essential for manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries seeking to improve interfacial adhesion, mechanical strength, and long-term durability.

Application

• Adhesive & Sealant Formulations: Acts as a key adhesion promoter and crosslinking agent, improving bond strength to glass, metals, and minerals.
• Reinforced Polymer Composites: Used as a surface modifier for glass fibers, silica, and other fillers to enhance compatibility and stress transfer within epoxy, phenolic, or polyurethane matrices.
• Specialty Coatings: Incorporated into primers and functional coatings to promote adhesion to difficult substrates and increase coating durability.
• Rubber Compounding: Serves as a coupling agent in silica-filled rubber systems (e.g., tires, industrial rubber goods) to reduce hysteresis and improve mechanical properties.
• Hybrid Material Synthesis: Utilized in the synthesis of organic-inorganic hybrid materials, sorbents, and catalysts due to its bifunctional (amine/vinyl) reactivity.
• Fiber Treatment: Applied as a sizing or finishing agent for technical textiles and fibers to impart specific surface functionalities.

Quality Control

Our production of N'-[3-(Trimethoxysilyl)Propyl]-n-[(Vinylphenyl)Methyl]Ethylenediamine adheres to stringent quality management protocols. Each batch undergoes comprehensive analysis including assay (by titration or NMR), identity confirmation (IR), and impurity profiling to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, color, density, and refractive index are available upon request, supporting your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat and incompatible materials.
