Polyetheramines are a class of diamine compounds whose ends are amine groups and whose main chain is a different molecular weight of polypropylene oxide / ethylene oxide. The D230 backbone is a polypropylene oxide group with two primary amine groups at both ends of the chain, the average molecule
The amount is about 230. Polyetheramine is an excellent epoxy resin curing agent and a key raw material for high performance composite materials. It has special properties such as low viscosity, high strength, high toughness and easy processing. Polyetheramines are used as shale inhibitors in composite materials, coatings, adhesives, waterborne electrophoretic paints and polyurea materials, modified epoxy curing agents for textile auxiliaries and waterborne epoxy coatings. It is widely used in wind turbine blade manufacturing, high-performance composite materials for lightweight automotive shells, shale oil and gas and marine oil and gas exploration, waterborne epoxy coatings, fuel additives, adhesives, high-speed railways, and marine engineering. In the field of automotive oil products, polyetheramine has the functions of cleaning oil circuit, reducing engine carbon deposit, reducing emissions, optimizing engine gasoline atomization effect, etc., and has become a mainstream oil additive. With the completion of oil upgrading work, The amount of etheramine used will be further increased.
