Processing
Pre Drying
Necessary low maximum residual moisture content: 0.15%
It is normally not necessary to dry HOSTAFORM. However, should there be surface moisture (condensate) on the molding compound as a result of incorrect storage, drying is required. A circulating air drying cabinet can be used for this purpose if the granul
The product can then be stored in standard conditions until processed.
Drying time (h):3 - 4
Drying temperature (℃):120 - 140
