Description

Triacetoxy(3-Chloropropyl)Silane is a bifunctional organosilicon compound that serves as a versatile coupling agent and intermediate. Its molecular structure combines reactive chloropropyl and acetoxysilane groups, enabling it to form durable bonds between organic polymers and inorganic substrates. This product is essential for manufacturers in the adhesives, sealants, coatings, and advanced materials sectors seeking to enhance composite performance, adhesion, and moisture resistance.

Application

• Surface Modification Agent: Used to treat glass fibers, minerals, and fillers to improve their compatibility and dispersion within polymer matrices like epoxy, polyurethane, and silicone.
• Adhesive & Sealant Formulation: Functions as an adhesion promoter and crosslinker in high-performance sealants, adhesives, and RTV silicone products, enhancing bond strength to various substrates.
• Coupling Agent for Composites: Critical in the production of fiber-reinforced plastics (FRP) and mineral-filled composites to increase mechanical strength and durability.
• Intermediate for Specialty Silanes: Serves as a key precursor in the synthesis of other functional silanes and silicone-based polymers with tailored properties.
• Waterproofing and Moisture-Curing Systems: Imparts water repellency and facilitates moisture-cure mechanisms in coatings and construction materials.

Quality Control

Our Triacetoxy(3-Chloropropyl)Silane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay (by GC or titration), identity confirmation (IR), and impurity profiling, to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) documenting purity, density, and refractive index is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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 after opening to prevent hydrolysis and degradation. Keep away from strong bases and oxidizing agents.
