Description

3-Aminopropyltris(Trimethylsiloxy)Silane is a bifunctional organosilicon compound featuring both an amino group and hydrolyzable siloxy groups. This unique structure makes it a highly effective coupling agent and surface modifier, bridging organic polymers with inorganic substrates. It is essential for manufacturers in the adhesives, sealants, coatings, and composites industries seeking to enhance material compatibility, adhesion, and mechanical properties. Its versatility also extends to applications in personal care and pharmaceutical formulations as a conditioning agent.

Application

• Coupling Agent: Promotes adhesion between organic polymers (e.g., epoxies, polyurethanes) and inorganic materials like glass, metals, and minerals in composites and filled plastics.
• Surface Modification: Used to treat silica, glass fibers, and other fillers to improve dispersion in polymer matrices and increase composite strength.
• Adhesives & Sealants: Enhances the bonding strength and moisture resistance of silicone-based and hybrid polymer adhesives.
• Coatings: Serves as an additive in primers and coatings to improve substrate wetting, corrosion resistance, and durability.
• Personal Care Ingredients: Functions as a conditioning agent in hair care and skincare products due to its ability to modify surface feel and provide film-forming properties.
• Pharmaceutical Intermediates: Utilized in the synthesis of drug delivery systems and as a surface modifier for controlled-release carriers.

Quality Control

Our production of 3-Aminopropyltris(Trimethylsiloxy)Silane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 and highly volatile nature, the container must be kept tightly sealed under dry conditions to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
