To accurately establish the exact expiry date, consult the box label. Out Life: the maximum accumulated time allowed at room temperature between removal from the freezer and cure. Prepreg should be stored as received in a cool dry place or in a refrigerator. After removal from refrigerator storage, prepreg should be allowed to reach room temperature before opening the polyethylene bag, thus preventing condensation. (A full reel in its packing can take up to 48 hours).
