Molecular synthesis and application of polyetheramine Polyetheramine is a high performance composite material. Polyetheramine can be used as a high performance curing agent for epoxy resin to produce high strength and high toughness composite materials. As a key component of polyurea materials, it is used in high-speed rail bridges. Waterproof systems for concrete structures such as bridges, dams, large venues, etc. have many application examples and show excellent performance; as coatings: they have a lower viscosity and can be used when used in epoxy floors or anticorrosive coatings.
