EPIKURE™ Curing Agent 3200 3223 3234 3245

Description

EPIKURE™ Curing Agents 3200, 3223, 3234, and 3245 are unmodified aliphatic amines. They are used in a variety of applications including epoxy curing agents. Due to their tendency to form complexes with atmospheric carbon dioxide, particularly in humid conditions, they are most often formulated, adducted or otherwise reacted to inhibit amine blush.

Benefits

  • As members of the ethylene amine family, they lend themselves to a wide variety of chemical reactions and enduse applications.
