Can 2-part lose its potency?

[gonzo620]

I’m hoping to make large batches of 2 part. 20 gallons of soda ash mix and 20 gallons of calcium chloride solution. Can or will potency be affected if stored for extended periods of time? 20 gallons of each should last me about 3-4 months.

I had some that sat in my garage for around 15 years and I used it.
