Description

(2-n-Benzylaminoethyl)-3-Aminopropyl-Trimethoxysilane,Tech-90 CAS NO 209866-89-7 is a high-purity, bifunctional organosilane coupling agent designed for demanding industrial applications. This compound is engineered to provide superior adhesion promotion and surface modification by creating strong covalent bonds between inorganic substrates and organic polymers. It is an essential raw material for manufacturers in the coatings, adhesives, and composites industries seeking to enhance product durability and performance. The Tech-90 grade signifies a technical quality optimized for cost-effective, large-scale production.

Application

• As a key coupling agent in fiberglass-reinforced plastics (FRP) and composite materials to improve the interfacial bond between glass fibers and polymer resins.
• Surface pretreatment for mineral fillers (e.g., silica, clay) to enhance their compatibility and dispersion in rubber and plastic compounds.
• Primer or additive in adhesive and sealant formulations to improve adhesion to difficult substrates like metals, glass, and painted surfaces.
• Modifier for epoxy, polyurethane, and acrylic coatings to increase corrosion resistance, wet adhesion, and overall coating durability.
• Treatment agent for glass microspheres and other hollow fillers used in lightweight composites and syntactic foams.
• Intermediate in the synthesis of more complex silane-based specialty chemicals and polymers.

Quality Control

Our (2-n-Benzylaminoethyl)-3-Aminopropyl-Trimethoxysilane,Tech-90 is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the defined technical specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and consistency for your production processes.

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 / 59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
