STORAGE:
Store DA 408 modified epoxy film adhesive in a contaminate free container and store at O degrees F for extended storage. For shorter storage time requirements store at 40 degrees F, this enables quicker stabilization times.
APPLICATION:
Remove material from cold storage at least 20 hours prior to use to allow for stabilization at room temperature. Keep the material wrapped to prevent moisture from condensing on the adhesive. If details are cut and replaced into cold storage, shorter stabilization times may be used.
Be sure parts to be bonded have been thoroughly cleaned and dried before bonding. Cut stabilized adhesive to part size, remove the poly separator and apply to part. Remove paper separator and join parts together. Parts are now ready to be bonded, and may be cured in a press, autoclave, or vacuum bag in oven..
CLEAN UP:
The adhesive can be removed from non-bonding areas with ketones or methylene chloride. Be sure to follow all Material Safety Data Sheet (MSDS) guidelines for the solvent to be used.
