General Information

EPIKURE Curing Agent 3388 is an effective curative for most types of epoxy resins.  It is compatible with both reactive diluent modified resins and standard liquid epoxy resins.  It has a convenient 3:2 mix ratio by volume when used with EPON Resin 828.  Table 1 lists the cured state and handling properties for a typical system cured with EPIKURE Curing Agent 3388. EPIKURE Curing Agent 3388 is compatible with and can be used in combination with most aliphatic and cycloaliphatic amine curing agents to modify handling characteristics or cured state properties.
