Definitions
Shelf Life: The maximum storage life for HexPly® 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.
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.
