Description

1-Propanamine, 2-(Dimethoxymethylsilyl)Oxy-3-3-(Trimethoxysilyl)Propoxy-n-3-(Trimethoxysilyl)Propyl- is a sophisticated, multi-functional organosilane coupling agent, CAS NO 127003-76-3. Its molecular architecture, featuring multiple alkoxysilyl and amine groups, provides exceptional reactivity and adhesion promotion between inorganic materials and organic polymers. This compound is essential for formulators and manufacturers seeking to enhance the mechanical properties, durability, and chemical resistance of composite materials and coatings. Its primary value lies in creating strong, stable interfaces in demanding industrial applications.

Application

• Adhesion Promoter for High-Performance Coatings: Used in automotive, aerospace, and industrial coatings to improve paint adhesion to metal, glass, and plastic substrates, especially under harsh environmental conditions.
• Surface Modifier for Fillers and Reinforcements: Treats silica, glass fibers, and minerals to enhance compatibility and dispersion within epoxy, polyurethane, and other polymer matrices, leading to stronger composites.
• Crosslinking Agent in Silicone and Sealant Formulations: Acts as a key ingredient to improve the cohesive strength, weather resistance, and adhesion of high-performance sealants and RTV silicones.
• Primer for Glass and Metal Bonding: Formulated into primers to prepare surfaces for structural bonding with adhesives, ensuring long-term bond integrity.
• Fiber Sizing for Composite Materials: Applied to glass or carbon fibers to protect filaments and improve the fiber-resin interfacial bond in advanced composite parts.
• Mineral Filler Treatment in Plastics: Enhances the mechanical properties and processability of filled thermoplastics and thermosets by reducing filler agglomeration.

Quality Control

Our production of 1-Propanamine, 2-(Dimethoxymethylsilyl)Oxy-3-3-(Trimethoxysilyl)Propoxy-n-3-(Trimethoxysilyl)Propyl- adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assay by titration or chromatography and identification by FT-IR. Certificates of Analysis (COA) detailing purity, specific gravity, and refractive index are provided and available upon request. Our quality commitment supports compliance with relevant industry standards for advanced material manufacturing.

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/59-77°F). 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, sparks, and open flame.
