How should I store HARE SQ negative epoxy?
The SQ resist series shows excellent resistance to temperature extremes in terms of performance and shelf life. It is recommended however that for best performance and resist life that the material be stored at room temperature. If refrigerated, bring up to room temperature before opening. Keep resist away from oxidizers, acids, bases and sources or ignition.
