Description

1,1'-[[3-(Triethoxysilyl)Propyl]Imino]Bis[3-Chloropropan-2-Ol] is a specialized organosilane coupling agent that integrates a reactive imino-bis-propanol core with chlorohydrin and triethoxysilyl functionalities. This unique molecular structure makes it a highly effective surface modifier and adhesion promoter, capable of forming strong covalent bonds between inorganic substrates and organic polymers. It is primarily utilized in advanced material science for developing high-performance composites, durable coatings, and specialty adhesives where enhanced interfacial bonding and moisture resistance are critical.

Application

• Adhesion Promoter for Coatings and Sealants: Enhances the bonding of epoxy, polyurethane, and acrylic coatings to glass, metal, and mineral surfaces, significantly improving durability and corrosion resistance.
• Surface Modification of Fillers and Reinforcements: Used to treat silica, glass fibers, and other mineral fillers to improve their compatibility and dispersion within polymer matrices like rubbers and engineering plastics.
• Crosslinking Agent in Silicone Polymers: Serves as a functional crosslinker or chain extender in the synthesis of modified silicone resins and elastomers, imparting specific mechanical and chemical properties.
• Intermediate for Specialty Chemical Synthesis: Acts as a key building block in the production of more complex silane derivatives, quaternary ammonium compounds, and other functional additives.
• Primer for Glass and Metal Bonding: Formulated into primers to prepare glass and aluminum surfaces for structural bonding with adhesives in automotive and aerospace assemblies.

Quality Control

Our production of 1,1'-[[3-(Triethoxysilyl)Propyl]Imino]Bis[3-Chloropropan-2-Ol] adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay by titration, identity confirmation via FT-IR, and impurity profiling, to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support 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 nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product performance. Keep away from strong acids, bases, and oxidizing agents.
