Description

N,N''-[(1,3-Dimethoxy-1,3-Dimethyldisiloxane-1,3-Diyl)Bis(2-Methylpropane-3,1-Diyl)]Bis(Ethylenediamine) is a specialized organosilicon compound featuring a unique hybrid structure that combines a disiloxane backbone with ethylenediamine functional groups. This molecular architecture makes it a valuable versatile intermediate and cross-linking agent in advanced material synthesis. It is primarily sought after by R&D and production teams in the silicone polymers, adhesives, and specialty coatings industries for developing materials with enhanced thermal and mechanical properties.

Application

• Silicone Polymer Modification: Acts as a functional cross-linker or chain extender to introduce amine functionality into silicone elastomers and resins, improving adhesion to various substrates.
• Advanced Adhesive Formulations: Used as a key intermediate in the synthesis of high-performance, moisture-curing adhesives and sealants with tailored flexibility and strength.
• Specialty Coating Precursor: Serves as a building block for creating hybrid organic-inorganic coatings that offer superior durability, corrosion resistance, and surface properties.
• Surface Treatment Agent: Utilized to modify surface characteristics of fillers (like silica) or other materials to enhance compatibility within polymer matrices.
• Pharmaceutical & Cosmetic Intermediates: Potential use in the synthesis of specialized siloxane-based compounds for controlled release or delivery applications.
• Research & Development: A critical reagent for academic and industrial research focused on novel organosilicon chemistry, dendrimers, and functional materials.

Quality Control

Our production of N,N''-[(1,3-Dimethoxy-1,3-Dimethyldisiloxane-1,3-Diyl)Bis(2-Methylpropane-3,1-Diyl)]Bis(Ethylenediamine) adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR, FT-IR, and GC/HPLC analysis, to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
