Product Description

Anti Corrosion Epoxy Curing Agent DH-3239 Hardener

DH-3239 provides dependable protection for concrete and steel surfaces exposed to corrosive conditions. The dense cured film blocks moisture, chlorides and chemical attack, extending the service life of floors, tanks and structural elements. Its low viscosity supports easy brush, roller or spray application.

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.
