Does flux need to be refrigerated?

I'm curious about the storage requirements for flux, specifically in relation to refrigeration. Is it necessary to refrigerate flux to preserve its integrity or maintain its performance? If so, what are the ideal conditions for storing flux in a refrigerated environment? Alternatively, are there any alternative storage methods that are suitable for flux without the need for refrigeration? Understanding the proper storage practices for flux is crucial in ensuring its effectiveness and avoiding any potential degradation over time.
