Product Description

No Blushing Epoxy Curing Agent DH-3239 Hardener

DH-3239 is engineered to eliminate amine blushing, a common defect in humid marine and coastal environments. The modified cycloaliphatic structure reacts cleanly with epoxy resin, leaving a glossy, tack-free surface even under high humidity. This makes it a reliable hardener for marine and anti-corrosion coating systems.

Frequently Asked Questions

What is the recommended mixing ratio of DH-3239 with epoxy resin?

The recommended ratio is 100 parts liquid epoxy resin to 50 parts DH-3239 by weight when the resin EEW is about 190 g/eq. Adjust proportionally for resins with different epoxy equivalent weights.

How long is the pot life of DH-3239 at 25℃?

The usable time of a 100g mix is around 30-50 minutes at 25℃. For large-area projects, prepare material in smaller batches to stay within the open time.

Can DH-3239 be used in self-leveling floor coating systems?

Yes. Its viscosity of 300-500 mPa﹥s allows excellent flow and leveling, producing smooth, bubble-free surfaces in self-leveling epoxy floors. It is one of the most common uses of this hardener.

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.
