APUG member keesbran has reported trouble using gum; so please, if you're interested in its use for gum, please be ready to experiment, it may not be a drop in replacement. I apologize for giving conflicting statements in the first post.

Kees also shared a note about refrigeration. From the freezer, DAS should be acclimated first in the refrigerator for 24 hours, and then at room temperature for "several" hours before opening. Condensation will harm it.

I learned from the supplier that DAS is prepared for industry with 3% water content. This compound is flammable if completely dessicated, but because of its 3% moisture content it is completely safe for normal handling. Basically, just don't expose DAS to open flames or hot surfaces.
