Amivion PEA-301 is a low-viscosity difunctional polyetheramine based on a polypropylene oxide backbone with an average molecular weight of approximately 230 g/mol. The product features two primary amine end groups, enabling reactive cross-linking with epoxy resins while imparting flexibility and toughness to cured systems. Amivion PEA-301 is used as a curing agent in epoxy coatings, adhesives, and composite laminates, as well as in polyurea chemistry and as an intermediate in the synthesis of polyamides and specialty chemicals. Its low viscosity and long pot life support processing in a wide range of application environments.
Key Features
- Low Viscosity for Easy Processing: Amivion PEA-301 exhibits a viscosity of approximately 9.5 cSt at 25°C, facilitating mixing, metering, and application in both manual and automated dispensing systems. This low viscosity also supports thorough wet-out of reinforcement materials in composite fabrication.
- Difunctional Primary Amine Structure: Two reactive primary amine groups per molecule provide efficient cross-linking with epoxy resins, yielding polymer networks with well-defined mechanical properties. This difunctionality also allows controlled use as a chain extender in polyurethane and polyurea chemistries.
- Flexibility and Impact Resistance in Cured Systems: The polypropylene oxide backbone of Amivion PEA-301 imparts flexibility and impact resistance to cured epoxy networks, making it suitable for applications requiring resistance to thermal cycling, mechanical shock, and substrate movement.
- Long Pot Life: Relative to conventional cycloaliphatic or aromatic amine hardeners, Amivion PEA-301 offers an extended pot life, providing a wider processing window for large-scale or complex lay-up operations in coatings, adhesives, and infusion processes.
- Broad Formulation Compatibility: Amivion PEA-301 is compatible with standard bisphenol A and bisphenol F epoxy resins and can be blended with other amine hardeners to tailor reactivity, mechanical properties, and processing characteristics for specific application requirements.
Typical Applications
Amivion PEA-301 is used as a reactive curing agent in epoxy systems for protective coatings, industrial flooring, and adhesive formulations where a balance of toughness, flexibility, and chemical resistance is required. Its low viscosity and long pot life make it well suited for vacuum-assisted resin infusion, filament winding, and pultrusion processes in composite manufacturing, where extended working time and thorough fiber wet-out are critical to laminate quality.
Beyond epoxy curing, Amivion PEA-301 serves as a reactive component in polyurea and polyurethane coatings and elastomers, reacting with isocyanates to form flexible, abrasion-resistant films. It is also used as a chemical intermediate in polyamide resin production, fuel and lubricant additive synthesis, corrosion inhibitor formulations, and wet-strength resins for the paper industry.
