Shin-Etsu KBE-903 (3-aminopropyltriethoxysilane) is a bifunctional silane coupling agent that bridges organic polymers and inorganic substrates via amino and ethoxy reactive groups. It enhances adhesion, mechanical strength, and environmental resistance in coatings, inks, and composites while improving filler dispersion. This colorless liquid offers fast hydrolysis and compatibility with diverse resins, including epoxy, acrylic, and rubber systems
Dual Reactivity - Amino groups bond with organics; ethoxy groups link to glass/metals
Performance Enhancement - Boosts wet/dry strength and electrical properties in composites
Moisture Resistance - Improves hydrolytic stability in humid environments
Multi-Matrix Compatibility - Effective with thermoplastics, thermosets, and elastomers
Processing Efficiency - Low viscosity for easy mixing and application
Coatings/Inks - Adhesion promoter for acrylic paints and metal primers
Composite Interfaces - Glass fiber reinforcement in epoxy/phenolic resins
Sealants/Adhesives - Binder for polysulfide, silicone rubber, and epoxy
Rubber Compounding - Filler treatment in nitrile/neoprene rubber
Electronic Encapsulation - Moisture-resistant protective coating
