Product Data Sheet Revised 12/21/06
Description

L-961 is a 140°F (60°C) curing, high strength, flame retardant, epoxy prepreg available on woven or unidirectional carbon fabrics such as 3K70P or T700 or as requested. L-961 is intended to be used as a single ply or multiple ply skin for complex or contoured laminates, custom moldings, foam cored or balsa cored panels, and for tooling prototypes.

Advantages of L-961
  • Low temperature cure coupled with high strength and toughness in this system make it ideal for complex shapes, molds or tools in the automotive, marine, and aerospace industries. Further, L-961 can be bonded directly to a variety of substrates for general purpose use.
  • Easy processing is another major advantage. L-961 can be cured with vacuum bag, press, or autoclave from 20 hours at 140°F (60°C) or in just 30 minutes at 225°F (107°C) with contact pressure. L-961 also exhibits excellent stability at elevated temperatures.
  • L-961 is also an excellent laminating prepreg where high impact strength and high toughness are required.
  • L-961 will find quick acceptance where unique designs or prototypes are being constructed. The low energy cure system allows for processing and lay-up without the aid of elevated temperature curing.
