 STORAGE:

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.

APPLICATION:

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.

CLEAN UP:

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.

CAUTION:

This material contains epoxy resins and amines which may cause irritation to sensitive skin. Avoid con-tact with eyes or skin. If contact with skin occurs, wash as soon as possible with soap and water. If con-tact with eyes occurs, flush with water for 15 minutes. Do not handle or use this material until Material Safety Data Sheet has been read and understood. The user of this material is required to use the necessary protective equipment as directed by applicable state and federal laws when handling, curing, and grinding this material.
