Introduction EPIKURE™ Curing Agent 3233 is an unmodified, T403-type polyoxypropylenetriamine that has

moderate reactivity, low viscosity, low color, low vapor pressure and high primary amine

content. It resists “blush”, “bloom” and “sweat-out” in epoxy compositions. EPIKURE

Curing Agent 3233 is a trifunctional primary amine curing agent with the idealized chemical

structure shown below.

Features · low viscosity and low vapor pressure

· light color and improved color retention compared to conventional amine-cured

epoxy systems

· long pot life

· improved flexibility and good impact resistance

Suggested Uses · Composites (Fiber reinforced products)

· General purpose casting and encapsulation

· Adhesive compounds

· Glaze and sealer high-build coatings

General Information EPIKURE Curing Agent 3233 is an effective curing agent for most types of epoxy resin. It is

compatible with modified epoxy resin blends and conventional bisphenol-A and bisphenol-F

epoxy resins. Table 1 lists the cured state and handling properties

EPIKURE Curing Agent 3233 is compatible and can be used in combination with most amine

curing agents (e.g. aliphatic and cycloaliphatic amines) and a wide range of modifiers (e.g.

nonylphenol) to adjust handling characteristics or cured state properties.

EPIKURE Curing Agent 3233 can be cured at room temperature or heat cured. Usually

accelerators (e.g., EPIKURE 3253 or EPIKURE 3234) are added to speed room temperature

cures.

Clean-out of EPIKURE 3233 in transfer lines and equipment can be accomplished with hot

water and steam since it is a water-soluble amine.
