Description

Ethylenediamine, n-[2-Methyl-3-(Trimethylsilyl)Propyl]- is a specialized organosilicon-modified diamine compound, identified by CAS NO 31024-48-3. This chemical is valued for its unique bifunctional reactivity, combining the chelating properties of an ethylenediamine backbone with the hydrophobic and silylating characteristics imparted by the trimethylsilylpropyl group. It serves as a critical intermediate and functional additive for advanced material synthesis, particularly in the silicone polymer and specialty coatings sectors. Industrial R&D and production teams in high-performance material manufacturing rely on its tailored properties to enhance product durability and functionality.

Application

• Silicone Polymer Modification: Acts as a cross-linking agent or chain extender to improve the mechanical strength, thermal stability, and adhesion properties of silicone elastomers and resins.
• Surface Treatment & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, or metals, promoting adhesion between organic polymers and inorganic substrates in composite materials.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key building block in the synthesis of complex molecules, leveraging its amine groups for further chemical transformations.
• Epoxy Curing Agent & Hardener: Functions as a curing agent for epoxy resins, contributing to improved flexibility and chemical resistance in the final cured network.
• Catalyst Ligand in Organometallic Chemistry: Utilized as a chelating ligand for metal catalysts in asymmetric synthesis and polymerization reactions.
• Corrosion Inhibitor Formulations: Incorporated into protective coatings and additives for metals, where its film-forming and barrier properties enhance corrosion resistance.

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 tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
