N-2-Aminoethyl-3-Aminopropyltrimethoxysilane (DAMO)

N-(2-Aminoethyl)-3-Aminopropyltrimethoxysilane (DAMO) is an amino-functional organosilane coupling agent featuring two reactive amine groups and three hydrolyzable methoxy groups. This dual functionality enables strong chemical bonding between organic polymers and inorganic substrates such as glass, metal, and mineral fillers.

It is widely used to improve adhesion, dispersion, and compatibility in composites, coatings, adhesives, and sealants. DAMO also enhances mechanical strength, moisture resistance, and corrosion protection in hybrid materials and surface treatments.

Key Features:

• Dual amine functionality for strong chemical bonding and reactivity

• Improves adhesion to glass, metal, and mineral surfaces

• Enhances dispersion of fillers and pigments

• Provides superior moisture resistance and corrosion protection

Applications:

• Adhesives, sealants, and coatings

• Glass fiber treatment and mineral-filled composites

• Epoxy, polyurethane, and polyamide resin modification

• Corrosion-resistant and protective coatings
