Product Description

Nonyl Phenol Free Epoxy Curing Agent DH-3239 Hardener

DH-3239 is formulated without nonyl phenol, responding to tightening environmental regulations in coating markets worldwide. Despite the clean formulation, it retains all the practical benefits of a modified cycloaliphatic amine: low viscosity, fast hardness build and excellent gloss. Manufacturers can upgrade their systems without compromising performance.

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.
