N-(3-Trimethoxysilylpropyl)ethylenediamine
N-(3-Trimethoxysilylpropyl)ethylenediamine (CAS: 1760-24-3) is a diamino-functional alkoxysilane supplied as a colorless to light yellow liquid. It is a widely used adhesion promoter and coupling agent that links organic polymers to inorganic surfaces, improving the strength and durability of coatings, adhesives, sealants, and composites on glass, metal, and mineral substrates. The two amine groups also enable epoxy and polyurethane curing chemistry, and the product finds use in foundry binders, tire cord treatment, and pigment surface modification. It is typically dosed at low levels and hydrolyzes in the presence of moisture. Customers select it where adhesion and wet-strength performance are critical.
• Adhesion promoter: couples resins to glass, metal, and mineral surfaces at low use levels.
• Coatings and sealants: improves wet adhesion, durability, and corrosion resistance.
• Curing chemistry: the diamine structure participates in epoxy and polyurethane curing.
• Other uses: foundry binders, tire cord treatment, and pigment surface modification.
