T31 epoxy hardener is an aliphatic amine-modified amine hardener. Through modification, it has a larger molecular weight, resulting in lower volatility. It is also a practically non-toxic compound, significantly enhancing safety during use. Due to the introduction of groups that promote epoxy resin curing during the modification process, it is possible to cure epoxy resins at lower temperatures.

Applicable
T31 Epoxy hardener is widely used in chemical construction anti-corrosion, coatings, adhesives, and more.
T31 hardener addition: The recommended dosage for 100 parts of E-44 epoxy resin is as follows for T31 hardener:
0℃ Usage: 25-30; 15℃ Usage: 18-22; 25℃ Usage: 16-20; T31 hardener
When using T31 hardener, epoxy resin can be diluted with ethanol, xylene, or acetone. The type and amount of diluent affect the curing speed, with the order being: ethanol > xylene > acetone. In higher temperatures, using T31 with acetone as a diluent can slow down the curing speed and extend the usable time. When mixing with phenolic resin, ethanol should be used as the diluent; acetone is not recommended.
