APCM SG 4528-029CU-102V

• 200ºF temperature cure capabilities
• Outstanding surfacing capabilities
• Low volatile content contributes to negligible surface porosity
• Excellent tack and handling properties for ease of lay-up
• Good environmental performance
• Compatible with a wide range of other epoxy prepreg systems
• Non-woven foil mesh qualified at many composite aircraft manufacturers
• Metal mesh capable of providing Zone 1A and Zone 2A direct effects lightning protection
• Provides a high degree of electromagnetic shielding for electric and magnetic fields associated with lightning and high powered radio frequency transmitters

• Remove material from cold storage at least 20 hours prior to use to allow for stabilization at lay up temperature conditions. Keep the prepreg sealed to prevent moisture from condensing on the prepreg. If details are cut and replaced in cold storage, the prepreg must be placed in sealed containers. Shorter stabilization times can be used with these details.
• Cut the material to size, peel back part of the release paper, this will expose the veil side of the prepreg.
• Apply the prepreg to the mold starting at one edge and proceed in a rolling motion and peeling away the release paper as the prepreg is applied to the mold.
• Next using a semi-flexible roller squeegee, and starting in the center, proceed in a uniform manner to push out any air pockets toward the outer edges. Alternately, palm hand pressure can be used to increase resin tack and effect conformability.
• Remove the polyethylene from the prepreg by peeling it back over itself minimizing lift off. It lift off occurs or if any air pockets are noticeable, place the poly liners back over the area and use the squeegee or hand pressure to workout the air pocket.
• Use your standard debulking procedure for 10 minutes.
• Continue the prepreg lay up.
• Debulking after each 3 plies is recommended.

Store prepreg at 0°F for maximum shelf life.
