Product Description

Fast Cure Epoxy Curing Agent DH-3239 Hardener

DH-3239 shortens the curing schedule of epoxy floor systems, helping facilities get back to work sooner. At 25℃, coated floors reach walkable hardness overnight and develop full mechanical strength within days — without sacrificing gloss or chemical resistance, so faster timelines never mean lower quality.

Frequently Asked Questions

Do you offer samples before bulk purchase?

We welcome sample requests so you can verify the performance of DH-3239 in your specific application prior to large-volume purchasing.

What payment and delivery terms do you offer?

We accept T/T payments and normally deliver within 5-8 working days after confirmation. Shipping is arranged from our plant in China.

Is DH-3239 suitable for electronic potting applications?

DH-3239 works well in electronic potting compounds where low viscosity, thermal stability and insulation performance are required.

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.
