Yes .So the shelf life of unopend activator is extended past 3 years?
Bottom line is we use to say 3 years once opened, now we say 2 years as we have no control over how it is stored.
Stable temps and the use of nitrogen would change everything.
Thanks Barry. I have been turning part A over every few months. For the last 2 months, I have been turning it every few days. Sometime this weekend, I will give it a test.I know you are concerned about the hardner, but have you stirred the part A at all? If not the bottom of the can is probably like half set concrete. I know SPI doesnt(or didnt in the past anyhow) recommend putting the Epoxy on a shaker, but after it sits that long, its about the only way I found to "bust it up".
