Product Description
Low Temperature Cure Epoxy Curing Agent DH-3239 Hardener

DH-3239 maintains a practical curing rate when temperatures drop, supporting winter construction schedules in cold climates. The formulation continues to build hardness and gloss at lower ambient conditions, with full properties reached after a longer cure window. Contractors can extend their working season with confidence.

Frequently Asked Questions
Does DH-3239 cause amine blushing or water spotting?
The modified cycloaliphatic structure of DH-3239 prevents amine exudation and water spotting, so the coating surface remains clean and uniform after cure.
What is the shelf life and how should DH-3239 be stored?
Sealed in its original container at 0-35℃, DH-3239 keeps for 24 months. Keep drums tightly closed and away from direct sunlight and moisture.
What packaging options are available for DH-3239?
The standard package is a 200kg drum. We also support flexible packaging configurations for bulk purchasing and export shipment.
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.
