Description

Siloxanes And Silicones, Di-Me, 3-(2-Aminoethyl)Aminopropylsilylidynetris(Oxy)Tris- is a specialized amino-functional siloxane oligomer, a key reactive intermediate in advanced material synthesis. Its bifunctional structure, featuring both siloxane and primary/secondary amine groups, provides a unique combination of surface activity, polymer compatibility, and reactivity. This compound is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of textile auxiliaries and personal care ingredients, where it acts as a coupling agent, adhesion promoter, and modifier to enhance performance properties.

Application

• Adhesion Promoter: Used as a key additive in primers, sealants, and adhesives to improve bonding to difficult substrates like glass, metals, and plastics.
• Surface Modifier & Coupling Agent: Imparts hydrophilic and reactive surface characteristics to inorganic fillers (e.g., silica, glass fibers) for improved dispersion and compatibility in polymer composites.
• Textile Finishing Agent: Serves as a softener and durable water repellent (DWR) finish for fabrics, providing a soft hand feel and enhanced performance.
• Epoxy & Polyurethane Modifier: Reacts with resin systems to act as a flexibilizer, impact modifier, and chain extender, improving toughness and chemical resistance.
• Personal Care Ingredient Intermediate: Utilized in the synthesis of silicone quats and other conditioning agents for hair care and skincare formulations.
• Release Coating Component: Incorporated into silicone release liner formulations to modify surface energy and anchorage.
• RTV Silicone Rubber Additive: Functions as an adhesion promoter and property modifier in room-temperature-vulcanizing (RTV) silicone sealants.

Quality Control

Our production of this amino-functional siloxane adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through analytical methods including FT-IR, NMR, and titration to confirm structure, amine value, and purity. A Certificate of Analysis (COA) detailing assay, viscosity, color, and specific gravity is provided with each shipment. We support customers requiring compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential viscosity changes or gelation. Separate from strong oxidizing agents.
