- Drying Conditions
It is preferred to use desiccant dryers, at reduced temperatures and drying times. 150°F for 2 hours is a target with dew point between -20°F and -40°F. Too high of temperatures and drying times will burn out the fragrance. In the absence of a desiccant dryer, the injection molding machine hopper may be used. Tray dryers may also be used.

- CURE - 40 – 70 sec.
- Tooling
The mold vent for the tool should be .002” to .003”. If this is not the case, mold temperatures could be elevated to help drive off volatiles thereby reducing surface blushing. (180°F – 220°F)
- Mold Temperature Regulation
Most molding thermolators use hot water as their medium. In the case of elevated mold temperatures as shown above, oil thermolators should be used as they can achieve high temperatures of 220°F and higher without turning to steam.
