Polyetheramine (PEA) is an amine-terminated polyether containing flexible polyether chains and reactive primary amine groups. It is generally a colorless to light yellow transparent liquid at room temperature and is widely used as an epoxy curing agent and reactive intermediate.
Dotachem supplies a range of Polyetheramine grades with different molecular weights, functionalities and amine values. These products are used in epoxy systems, coatings, adhesives, sealants, composite materials and elastomers. By selecting a suitable grade, formulators can adjust curing performance, flexibility, toughness and processing properties according to specific application requirements.

Is Dotachem a Polyetheramine supplier in China?
Yes. Dotachem supplies Polyetheramine from China for customers in different industrial markets. Available grades include D230, D430, D440, D2000 and T5000. Dotachem has experience serving customers in more than 50 countries and regions worldwide.
What is the difference between Polyetheramine D230 and D2000?
Both D230 and D2000 are difunctional polyetheramines, but they differ significantly in molecular weight. D230 has a lower molecular weight and higher amine content, while D2000 has a much longer polyether chain and is more suitable for systems where flexibility and toughness are important.
How do I choose a Polyetheramine grade?
Grade selection depends on molecular weight, functionality, amine value, required reactivity and the desired properties of the final system. Lower molecular weight grades generally provide higher amine content and reactivity, while higher molecular weight grades can provide greater flexibility.
Can Polyetheramine be used as an epoxy curing agent?
Yes. Polyetheramine is widely used as an epoxy curing agent. Different grades provide different levels of reactivity, flexibility and crosslinking, allowing selection according to the processing and performance requirements of the epoxy system.
