Calcium chloride for two part

[Defuse]

I am looking for a new source to get my calcium chloride. Living in the south makes it very difficult to find Prestone Driveway heat that many use. I have found this stuff and wanted to see if others think it would be ok to use. This is the MSDS and a picture of the product.

We can't tell if it is adequately pure, but it is the right material.

That being said my options are to send it off to get tested (expensive?) or roll the dice and see what happens. Quite the quandary, especially if I am wrong and roll the dice.

Roll it slowly, starting slow to watch for problems. It is more likely OK than not.

If you can find the Tetra Flake locally, I can recommend it, as I have been using it since January without issue. I picked it up a Leslie's Pool Supplies.
