CA shelf life

This all makes sense. I'm going to play it safe and pick up some fresh. Thanks again

That's fine. In your past experience what happened if you didn't refrigerate the glue after cleaning the tip of the bottle and closing it up tightly to exclude moisture? I'm not being argumentative but my CA glue has never gone bad or aged. All CA glues are CA glues so we should all have the same products. Information from the American Chemical Society, but there isn't any mention of heat instability, but water causes it to polymerize rapidly.

When I began using CA glue for pen turning I bought quantities larger than the "little tubes" and was advised to refrigerate it after opening.
