Description

3-Chloropropylsilanetriol is a highly reactive organosilicon intermediate featuring a hydrolytically sensitive silanetriol group and a terminal chloroalkyl functionality. This unique bifunctional structure makes it a critical building block for the synthesis of advanced silane coupling agents and surface modifiers. It is essential for manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to enhance interfacial adhesion between organic polymers and inorganic substrates.

Application

• Silane Coupling Agent Precursor: Serves as a key intermediate for synthesizing a wide range of specialty silanes used to bond organic polymers to glass, metals, and minerals.
• Surface Modification: Used to functionalize silica, nanoparticles, and other inorganic fillers to improve dispersion and compatibility within polymer matrices.
• Adhesives and Sealants: Imparts improved moisture resistance and adhesion strength in high-performance formulations.
• Composite Materials: Enhances the mechanical properties of fiberglass-reinforced plastics (FRP) and mineral-filled composites by strengthening the filler-matrix interface.
• Coatings: Employed in primers and functional coatings to promote adhesion to difficult substrates.
• Crosslinking Agent: Acts as a crosslinker in silicone resin systems and other polymer networks.

Quality Control

Our 3-Chloropropylsilanetriol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and purity, meeting the high standards required for industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for extended stability.
