Description

n-[(3-Trimethoxysilyl)Propyl]Ethylenediamine Triacetic Acid Trisodium Salt is a highly functionalized organosilane chelating agent, combining the robust adhesion properties of a silane coupling agent with the powerful metal-chelating capability of an EDTA derivative. This dual functionality makes it a critical component for creating advanced, multifunctional surfaces and materials. It is essential for industries requiring precise control over metal ion interactions at interfaces, such as in specialty coatings, advanced composites, and high-performance water treatment systems.

Application

• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces (glass, silica, metals) with chelating groups, promoting adhesion in composite materials and coatings.
• Metal Ion Sequestration in Coatings: Incorporated into paint, resin, and coating formulations to chelate and deactivate trace metal ions that can cause instability, discoloration, or premature curing.
• Advanced Water Treatment: Employed in selective filtration media or membranes designed to remove specific heavy metal ions from industrial wastewater.
• Chromatography & Separation Science: Serves as a ligand for preparing chelating stationary phases used in immobilized metal affinity chromatography (IMAC) for protein purification.
• Adhesive & Sealant Formulations: Enhances the bond strength and durability of adhesives, especially on metal substrates, by improving wetting and providing corrosion inhibition at the interface.
• Catalyst & Polymer Stabilizer: Acts as a ligand for metal catalysts or as a stabilizer in polymer systems to prevent metal-catalyzed degradation.

Quality Control

Our production of n-[(3-Trimethoxysilyl)Propyl]Ethylenediamine Triacetic Acid Trisodium Salt adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay (by titration or HPLC), identification (IR, NMR), and impurity profiling, to ensure consistency and high purity suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
