Storage & Handling
- Storage Conditions
- Do not store outdoors. Keep dry at ambient temperature.
- Avoid humid environment, heat and direct sunlight.
- Use material as soon as possible after the delivery, in order to prevent possible material quality deterioration.
- Pre-dry of the unopened PBST SA916F is not necessary.
- It is recommended to keep packages sealed until ready to process and using up the whole 25-kg bag.
- Unused material should be tightly sealed, kept away from open air, and pre-dried (at 60°C for over 5 hours) to moisture content of less than 1,000 ppm (preferable less than 500 ppm) prior to using next time.
