Amivion AEEA is aminoethylethanolamine (AEEA), a bifunctional aliphatic amine with the chemical structure 2-(2-aminoethylamino)ethanol (CAS 111-41-1). The molecule contains a primary amine group, a secondary amine group, and a hydroxyl group within a short-chain ethylamine backbone, giving it a unique combination of reactivity with epoxy resins and compatibility with aqueous and polar solvent systems. The presence of the hydroxyl group alongside the amine functions reduces vapor pressure compared to simple aliphatic diamines, improves water miscibility, and contributes to enhanced adhesion and compatibility in waterborne epoxy and polyurethane systems. Amivion AEEA is used as a reactive curing agent building block, a corrosion inhibitor precursor, a chelating agent intermediate, and a functional additive in textile, paper, and specialty chemical applications.
Key Features
- Bifunctional Reactivity — Amine and Hydroxyl Groups: Amivion AEEA carries both reactive amine groups (primary and secondary) and a hydroxyl group in a single molecule. In epoxy curing applications, the primary and secondary amines react with epoxide groups to form a cross-linked network, while the hydroxyl group contributes to adhesion and compatibility. This multifunctionality makes AEEA a useful building block for modified amine and waterborne curing agent formulations.
- Good Water Miscibility and Waterborne Compatibility: The hydroxyl group in Amivion AEEA increases its polarity and water miscibility compared to purely hydrocarbon-backbone aliphatic amines. This property supports its use as a component in waterborne epoxy curing agent formulations, aqueous corrosion inhibitor solutions, and water-reducible amine adduct systems designed for low-VOC coating applications.
- Lower Vapor Pressure than Simple Aliphatic Amines: The presence of the hydroxyl group reduces the volatility of Amivion AEEA relative to short-chain aliphatic amines of similar molecular weight. Lower vapor pressure reduces amine vapor exposure during handling and application, which is relevant to workplace safety in coating and adhesive operations.
- Versatile Synthesis Intermediate: Amivion AEEA serves as a building block in the synthesis of modified amine curing agents, chelating agents, surfactants, and specialty chemicals. The combination of amine and hydroxyl reactivity allows controlled derivatization to produce adducts, imidazolines, or ethoxylated derivatives tailored for specific performance requirements in downstream applications.
- Corrosion Inhibition Functionality: Amine compounds based on AEEA chemistry are used in corrosion inhibitor formulations for ferrous and non-ferrous metals in aqueous systems, metalworking fluids, and coatings. The combination of amine and hydroxyl groups supports adsorption onto metal surfaces and formation of a protective barrier against corrosive media.
Typical Applications
Amivion AEEA is used across several industrial application areas. In epoxy coatings and adhesives, AEEA serves as a reactive amine component or building block for modified amine and amine adduct curing agents, particularly in waterborne and low-VOC epoxy systems. Its hydroxyl and amine functionality supports formulation of waterborne epoxy curing agents with improved compatibility and reduced blush tendency. In corrosion protection, AEEA is used as a component in metalworking fluid formulations, rust inhibitors for steel and other metals, and corrosion-inhibiting primers where its metal-adsorption properties are valuable.
Additional applications include use as an intermediate in the manufacture of chelating agents and specialty surfactants; as a textile and fiber processing auxiliary for improving dye fixation and surface wettability; as a paper processing additive for wet-strength resin production; and as a component in agricultural formulations and personal care ingredient synthesis. Amivion AEEA is also evaluated as a reactive modifier for improving the hydrophilicity and adhesion properties of amine-based polymer systems in industrial and specialty chemical formulations.
