Polyetheramine D400 Curing Agent
CAS Number: 9046-10-0
Polyetheramine D400 is a medium-molecular-weight (Mn ~400 g/mol) difunctional aliphatic amine with a longer polyoxypropylene chain than D230, providing higher flexibility, longer working time, and reduced exotherm in epoxy cure reactions. Its low volatility and reduced skin-sensitization potential compared to aromatic amines make it safer for industrial use. D400 is preferred for thick-section adhesives, civil engineering applications, and highly flexible epoxy systems.
