STORAGE CONSIDERATIONS
Storage in a low humidity environment is preferred. Large high
density plastic packages are moisture sensitive and should be
stored in Dry Vapor Barrier Bags. Prior to usage, the parts
should remain bagged and stored below 40
°
C at 60%RH. If the
parts are removed from the bag, they should be used within 48
hours or stored in an environment at or below 20%RH. If the
above conditions cannot be followed, the parts should be baked
for four hours at 125
°
C in order remove moisture prior to
soldering. Sipex ships product in Dry Vapor Barrier Bags with a
humidity indicator card and desiccant pack. The humidity
indicator should be below 30%RH.
