Catalyst Mixing Guide

Hardener 50%
I was using cups for mixing catalyst and resin in small amounts. Because I was mixing by estimated volume of resin, the amount of drops to use was not always accurate. I had to apply heat to kickstart curing on one or two occasions, but the catalyst worked well.
From what I read, catalyst has a short shelf life. I was using resin that was years old, and it would not harden with the old catalyst. This catalyst did make the old resin harden. It would be helpful to have shelf life guidance with this product, along with any hints that would make it stay viable longer.
