5. PACKING AND STORAGE
25 kilogram paper bag or PE bag; stored in a cool dry indoor place at temperature of-20℃ to 35℃. Avoid long-term exposure to direct sunlight. The shelf life of the resin isone year in the above-mentioned storage conditions. Experience has shown that storagelife of the resin is up to 3 years. It is proposed that the testing product beyond the shelf lifecan still be used after tested qualified.
Note: The above-mentioned indications are based on carefully made tests. Noliability can be assumed in the event of any inaccuracy or incompleteness being found inthe value listed above and consequently we recommend evaluation in your ownlaboratories prior to use.
