Product Data Sheet Revised 3/17/09
Description
L-303 is a 250°F (121°C) curing, high peel strength, flame retardant, modified epoxy film adhesive. L-303 is intended to be used for structural bonding of aluminum, fiberglass, aramid, and other structural materials to themselves and to various types of core materials such as aluminum, aramid/phenolic, PVC foam, and paper for sandwich construction.
Advantages of L-303
  • The high peel strength and high toughness of L-303 allow the designer to use this material in high abuse areas such as aircraft interiors, cargo systems, marine structural bulkheads, etc.
  • L-303 is very easy to process through a wide variety of cure temperatures and pressures. Curing may occur in autoclave, press, or vacuum bag from 90 minutes at 235°F (113°C) or in just 40 minutes at 275°F (135°C) with contact pressure (235°F temperatures are recommended for urethane or PVC core).
  • With dry subcomponents, ‘in-hot / out-hot’ press cycles may be developed by the user.
