Product Data Sheet Revised 12/20/06
Description

L-575TG is a 175°F (79°C) curing, high peel strength, flame retardant, epoxy prepreg available on fiberglass fabrics such as 7781 style or other styles as requested. L-575TG is intended to be used as a single ply or multiple ply skin for foam-cored panels or balsa-cored panels.

Advantages of L-575TG
  • No adhesive is required because of the high peel strength and high toughness of the L-575 resin matrix. L-575TG can be bonded directly to a variety of core materials.
  • Easy processing is another major advantage. L-575TG can be cured with a vacuum bag, press, or autoclave type cures from 8 hours at 160°F (71°C) or in just 30 minutes at 250°F (121°C) with contact pressure (175°F cure temperatures are suggested for urethane, balsa or PVC core).
  • L-575 is also an excellent laminating prepreg when high impact strength and high toughness are required.
