Description

4-(Diethoxymethylsilyl) Butylamine is a bifunctional organosilane coupling agent featuring both an alkoxysilyl group and a primary amine functionality. This unique structure makes it a critical intermediate for creating covalent bonds between inorganic materials and organic polymers, enhancing composite performance. It is essential for manufacturers in the adhesives, sealants, coatings, and advanced materials sectors seeking to improve adhesion, mechanical strength, and durability.

Application

• As a coupling agent and adhesion promoter in epoxy, polyurethane, and acrylic-based adhesives and sealants.
• Surface modification of glass fibers, minerals, and metal oxides to improve resin compatibility and interfacial bonding in composite materials.
• Key intermediate in the synthesis of specialty silicones and functional polymers for coatings with enhanced corrosion resistance and weatherability.
• Used as a crosslinking agent or chain extender in polymer formulations to tailor material properties.
• Surface priming agent for improving paint and coating adhesion on difficult substrates like metals and plastics.
• Potential applications in the formulation of release coatings and as a modifier for silica in tire and rubber compounds.

Quality Control

Our production of 4-(Diethoxymethylsilyl) Butylamine adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by GC or titration, identity confirmation (IR), and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your material specifications.

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 compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity.
