Name: AB Specialty Silicones Andisil 1120 N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of AB Specialty Silicones Andisil 1120 N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilane

Bifunctional amino silane with two distinct primary amine groups—ethylene diamine (β-aminoethyl) and aminopropyl (γ-aminopropyl)—enabling dual reactivity for enhanced coupling efficiency.
Trimethoxy functionality provides rapid hydrolysis and strong covalent bonding to hydroxylated surfaces including glass, metals, and mineral fillers.
High amine content ensures superior adhesion promotion in epoxy, phenolic, and polyurethane resin systems.
Low volatility and favorable handling characteristics compared to chlorosilane alternatives, supporting safer industrial processing.
Compatible with aqueous and solvent-based formulations, offering flexibility in primer, coating, and composite manufacturing.

Typical Applications Of AB Specialty Silicones Andisil 1120 N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilane

Adhesion promoter in structural adhesives and epoxy-based bonding agents for automotive and aerospace composites.
Surface modifier for silica, clay, and calcium carbonate fillers in high-performance rubber and thermoplastic compounds.
Primer component for metal and glass substrates prior to painting, powder coating, or laminating processes.
Reactive additive in moisture-curable sealants and RTV silicones to improve substrate wetting and interfacial strength.
Functionalization agent for bioactive glass and ceramic particles in dental and biomedical material formulations.
