Description

Siloxanes And Silicones, 3-(2-Aminoethyl)Aminopropyl Me, Di-Me, Methoxy-Terminated is a specialized amino-functional siloxane oligomer, a key reactive intermediate in silicone chemistry. Its bifunctional nature, combining amino and methoxy groups, provides exceptional reactivity and adhesion promotion for demanding industrial formulations. This product is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance material performance and durability.

Application

• Adhesion Promoter: A critical component in primers and coupling agents for bonding silicone and organic polymers to difficult substrates like metals, glass, and plastics.
• Surface Modification: Used to impart amino functionality to surfaces (e.g., silica, fillers) for improved dispersion and compatibility in composite materials.
• Crosslinking Agent: Functions as a reactive intermediate in the synthesis of modified silicones, polyurethanes, and epoxy resins, enhancing mechanical properties.
• Textile & Fiber Treatment: Provides durable softness, hydrophilicity, and anti-static properties to synthetic and natural fibers.
• Personal Care & Cosmetic Ingredients: Serves as a conditioning agent and emulsifier in hair care and skincare formulations, improving feel and stability.
• Release Coatings: A modifying agent in silicone-based release coatings for pressure-sensitive adhesives and industrial molding.

Quality Control

Our production of this amino-functional siloxane adheres to strict quality management systems. Every batch is characterized using advanced analytical techniques to ensure consistency in amine value, viscosity, and methoxy content. Certificates of Analysis (COA) detailing key specifications are provided to guarantee the material meets your formulation requirements and supports your own quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain optimal reactivity.
