Storage & Handling
- Storage and Handling
Store the product with the roll core sitting horizontally and support at core ends in its original (or equivalent) sealed packaging at 0°F (-18°C). Prevent condensation on the product by warming to room temperature before opening vapor barrier bag (reseal for subsequent storage). The usual precautions when handling uncured synthetic resins and fine fibrous materials should be observed. See Material Safety Data Sheet. The use of clean disposable impervious gloves provides protection for the operator and avoids contamination of material and
components.
