Processing
Pre Drying
Necessary low maximum residual moisture content: 0.02%
 
To avoid hydrolytic degradation during processing, CELANEX resins have to be dried to a moisture level equal to or less than 0.02%. Drying should be done in a dehumidifying hopper dryer capable of dewpoints <-40℉ (-40℃) at 250℉ (121℃) for 4 hours.
 
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100℃.
 
Drying time (h):4
Drying temperature (℃):120 - 130
