T31 epoxy resin hardener is an amine-type hardener modified with aliphatic amines. Through modification, it has a larger molecular weight, resulting in lower volatility. It is also a practically non-toxic compound, significantly enhancing safety for 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.

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 curing speed being: ethanol > xylene > acetone. In higher temperatures, when using T31, using acetone as a diluent can reduce the curing speed and extend the usable time. When mixing epoxy resin with phenolic resin, it is recommended to use ethanol as the diluent and avoid using acetone.
