Ethylene Amines - epoxy cure agents
Ethylene amines are used in the Chemical, Agricultural, Pharmaceutical, Paper and Paint industries. They are water soluble and slightly viscous liquids with ammoniacal odour and chemical reactivities. These chemical reactivities are dependent upon primary and secondary amino groups. For coatings applications they are offered as Epoxy Curing Agents.
