Product Data Sheet Revised 12/20/06
Description

L-701 is a 250°F (121°C) curing, high peel strength, flame retardant, epoxy prepreg available on aramid fabrics such as 285 style or other styles as requested. L-701 is intended to be used as a single ply or multiple ply skin for aramid/phenolic honeycomb, aluminum honeycomb or PVC foam core sandwich panels.

Advantages of L-701
  • No adhesive is required because of the high peel strength and high toughness of the L-701 resin matrix. L-701 can be bonded directly to a variety of core materials.
  • Easy processing is another major advantage. L-701 can be cured with vacuum bag, press or autoclave type cures from 90 minutes at 235°F (113°C) or in just 40 minutes at 275°F (135°C) with contact pressure (235°F (113°C) cure temperatures are recommended for urethane or PVC core).
  • L-701 is also an excellent laminating prepreg when high impact strength and toughness are required.
