Description

n-Benzylidene-3-(Trimethoxysilyl)Propylamine is a specialized organosilane coupling agent featuring both an amine and a methoxysilyl functional group. This bifunctional structure is critical for creating strong, durable bonds between organic polymers and inorganic substrates like glass, metals, and minerals. It is essential for formulators and material scientists in industries requiring enhanced adhesion, surface modification, and composite material performance.

Application

• Adhesion Promoter in epoxy, polyurethane, and acrylic-based coatings, sealants, and adhesives for demanding substrates.
• Surface Modifier for glass fibers, minerals (e.g., silica, clay), and metal oxides to improve compatibility with polymer matrices.
• Key Intermediate in the synthesis of advanced silane-based crosslinkers and functional polymers.
• Filler Treatment to enhance the dispersion and mechanical properties of mineral-filled composites and rubber compounds.
• Corrosion-Resistant Coatings as a component in primers and pretreatments for metals like aluminum and steel.
• Waterproofing Agent in construction materials and stone protectants.

Quality Control

Our production of n-Benzylidene-3-(Trimethoxysilyl)Propylamine adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure consistency and performance. Certificates of Analysis (COA) with detailed specifications are provided to guarantee supply reliability and product traceability for your formulation 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation from moisture absorption.
