Product Description
Long Pot Life Epoxy Curing Agent DH-3239 Hardener
With a practical 30-50 minute pot life at 25℃, DH-3239 gives applicators the working time needed to cover large floor areas without waste. Its steady cure profile lets several workers apply from the same mix in sequence, producing an even, well-leveled floor with consistent appearance across the full surface.

Frequently Asked Questions
Is DH-3239 free of nonyl phenol?
Yes, DH-3239 is a nonyl phenol free formulation, meeting modern environmental and safety requirements for coating raw materials.
What curing schedule is needed to reach full performance?
Full properties develop after roughly 7 days at 25℃. Post-curing at 60-80℃ for several hours can speed up the process when faster turnaround is required.
Which substrates can DH-3239 epoxy systems bond to?
DH-3239 systems bond firmly to concrete, cement mortar, steel, aluminum and most prepared industrial substrates, provided the surface is clean, dry and properly primed.
Do you offer samples before bulk purchase?
We welcome sample requests so you can verify the performance of DH-3239 in your specific application prior to large-volume purchasing.
What payment and delivery terms do you offer?
We accept T/T payments and normally deliver within 5-8 working days after confirmation. Shipping is arranged from our plant in China.
Is DH-3239 suitable for electronic potting applications?
DH-3239 works well in electronic potting compounds where low viscosity, thermal stability and insulation performance are required.
