3-Aminopropyltriethoxysilane (AMEO / APTES)

3-Aminopropyltriethoxysilane (AMEO / APTES) is an amino-functional organosilane coupling agent containing a reactive primary amine group and three hydrolyzable ethoxy groups. This dual functionality enables the formation of strong covalent bonds between organic polymers and inorganic materials, enhancing interfacial adhesion, dispersion, and durability.

AMEO / APTES is widely used as an adhesion promoter, surface modifier, and coupling agent in coatings, adhesives, sealants, and composite applications. It significantly improves mechanical strength, corrosion resistance, and moisture protection in treated systems.

Key Features:

• Excellent adhesion promoter for glass, metal, and mineral substrates

• Improves mechanical properties and durability of composite materials

• Enhances corrosion resistance and water repellency

• Compatible with epoxy, polyurethane, and phenolic resin systems

Applications:

• Adhesives, sealants, and coatings

• Glass fiber and mineral surface treatments

• Composite and filler modification

• Epoxy and polyurethane resin systems
