Precautions for storage and handling
・ Since this is a fine powder, use rubber gloves, dust masks, protective eyewear and other
protective gear when handling it in order to protect skin and eyes.
・ When handling large
amounts of it, install dust collection equipment. In addition, since there is a danger of dust explosions
occurring from ignition caused by static electricity sparks, use grounding equipment and conductive dust
filtration cloth and take other countermeasures.
・ Store in a place where it will not be
dampened by rain, for example, because it could dissolve. Moreover, because it can easily harden into
blocks if it absorbs moisture, avoid storing it in hot and humid conditions.

Precautions for storage and handling
・ Casting grade of Nichigo G-Polymer™ that has water content of less than 0.5 wt%, in
a moisture-resistant package, so there is no need to pre-dry it before casting.
・ Nichigo
G-Polymer™ is an absorbent resin. If its package is left open for a long period of time, it could
absorb moisture and this could result in foaming at the time of casting. Use heat-sealing to hermetically
seal the package for storage.
・ Redrying is not recommendable, because it could cause
yellowing, F.E., etc.
・ To the greatest extent possible, avoid leaving Nichigo G-Polymer™
in processing equipment. Doing so could result in foaming and gelification. When stopping processing,
purge it with LDPE or LLDPE. Consider approximately 20 minutes to be the maximum amount of time that it
should be left in equipment.
