Name: Shin-Etsu KBE-603 N-(2-Aminoethyl)-3-aminopropyltriethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Shin-Etsu KBE-603 N-(2-Aminoethyl)-3-aminopropyltriethoxysilane

Bifunctional amino silane with two distinct primary amine groups—ethylene diamine-type (–CH₂CH₂NH₂) and propylamine-type (–CH₂CH₂CH₂NH₂)—enabling versatile covalent coupling to both organic polymers and inorganic surfaces.
Triethoxysilyl group provides excellent hydrolytic reactivity and strong condensation bonding with metal oxides, glass, silica, and other hydroxylated substrates.
High purity and low volatility formulation ensures consistent performance in precision coating, adhesive, and composite manufacturing processes.
Enhanced compatibility with epoxy, phenolic, and polyurethane resin systems due to balanced hydrophilicity and organophilicity.
Supports improved interfacial adhesion, moisture resistance, and long-term durability in demanding environmental conditions.

Typical Applications Of Shin-Etsu KBE-603 N-(2-Aminoethyl)-3-aminopropyltriethoxysilane

Adhesion promoter for epoxy-based structural adhesives and potting compounds used in automotive electronics and EV battery modules.
Surface modifier for silica fillers and glass fibers in high-performance thermoset composites (e.g., wind turbine blades, aerospace components).
Functional additive in waterborne coatings and primers for metal and concrete substrates requiring corrosion inhibition and enhanced film integrity.
Coupling agent in rubber-to-metal bonding systems, particularly for dynamic sealing and vibration-damping applications.
Key ingredient in silicone-modified hybrid sol-gel formulations for anti-reflective and self-cleaning optical coatings.
