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.
