AI Technical Summary
Existing epoxy resin systems face challenges in achieving a long pot life at room temperature, fast reactivity at elevated temperatures, and excellent mechanical properties, particularly high tensile strength and tensile strain, due to the incompatibility of anhydride and amine curing agents.
A curable epoxy system combining polyether amine modified epoxy resin with both anhydride and amine curing agents, optionally with an amphiphilic block copolymer as a toughener, to create a composition that offers a long pot life, fast reactivity, and improved mechanical properties.
The system provides a curable epoxy resin with a gel time of at least 6 hours at room temperature, fast curing at elevated temperatures, and enhanced mechanical properties, including high tensile strength and strain, suitable for applications like fiber reinforced polymer composites and coatings.
