Store material in a contaminate free container and store a 0ºF for extended storage. For shorter storage time requirements store at 40ºF, this enables quicker stabilization and less condensation build up on material.


Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep material wrapped to prevent moisture form condensing on the prepreg.


The uncured adhesive can be removed from no-bonding areas with ketones or methylene chloride. Be sure to follow all Material Safety Data Sheet (MSDS) guidelines for the solvent to be used.
