Definitions:
Tack Life: The time, at room temperature, during which prepreg retains enough tack for easy component lay-up.
Out Life: The maximum accumulated time allowed at room temperature between removal from the freezer and cure.
Shelf Life: The maximum storage life for HexPly® M21 prepreg, from date of manufacture, when stored continuously, in a sealed moisture-proof bag, at -18 °C (0 °F). To accurately establish the exact expiry date, consult the box label.
