Description

2,2,9,9-Tetramethyl-7-Tetradecyl-6-[(Trimethylsilyl)Oxy]-3,8-Dioxa-2,9-Disiladecan-5-Amine is a specialized organosilicon amine compound, valued for its unique bifunctional structure that combines silyl ether and amine groups. This chemical is engineered to serve as a high-performance coupling agent, surface modifier, and reactive intermediate in advanced material synthesis. It is primarily required by manufacturers in the silicone polymers, specialty coatings, and advanced composites industries seeking to enhance material compatibility and adhesion.

Application

• Silicone Polymer Modification: Acts as a functional monomer or chain extender to introduce amine functionality into polysiloxane backbones, improving cross-linking and thermal stability.
• Adhesion Promoter for Coatings: Used in primer formulations for metals, glass, and plastics to significantly improve the adhesion of silicone-based and epoxy coatings.
• Surface Treatment Agent: Modifies the surface of inorganic fillers (e.g., silica, glass fibers) to enhance dispersion and interfacial bonding in polymer composites.
• Pharmaceutical & Cosmetic Intermediates: Serves as a key synthetic building block for siloxane-based active ingredients or delivery agents, leveraging its hydrolytic stability.
• Release Coatings & Sealants: Imparts controlled release properties and improved mechanical strength in silicone sealants and pressure-sensitive adhesives.
• Lubricant & Grease Additive: Functions as a polar additive in synthetic lubricants to improve film strength and reduce wear on metal surfaces.

Quality Control

Our production of 2,2,9,9-Tetramethyl-7-Tetradecyl-6-[(Trimethylsilyl)Oxy]-3,8-Dioxa-2,9-Disiladecan-5-Amine adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including NMR, FT-IR, and HPLC, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all critical parameters are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 strong acids and oxidizing agents.
