Note: The above analytical data are not specifications.

For swelling resistant articles based on NBR and CR. The swelling behavior of Faktis Corona Q in mineral oils is comparable to that of articles based on 33 % ACN-NBR; consequently Corona Q improves the oil resistance in articles containing 18 to 28 % ACN-NBR or CR.

 Store in originally sealed packaging in cool, dry places. Maximum recommended storage temperature: 25°C
Shelf Life is min. 6 months under the recommended storage conditions.
