Product Description
Water Spot Resistant Epoxy Curing Agent DH-3239 Hardener

Water spots and hazy patches can spoil a floor when conventional amine hardeners cure in humid conditions; DH-3239 prevents them. The modified formulation reacts fully and evenly, keeping the finished floor uniform and glossy — a practical choice for coastal regions and high-humidity production facilities.

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.
