Description
LC-E334 is a single or two side coated, 350⁰F (177⁰C) epoxy glass prepreg which exhibits excellent performance at temperatures up to 400⁰F (204⁰C). LC-E334 has proven to be ideal where a higher Tg is required along with additional toughness.
Advantages
LC-E334 is ideal for multi ply laminates or sandwich structures requiring an elevated Tg. Excellent strength and toughness allow for LC-E334 to perform well in a variety of finished part shapes and sizes. Low volatiles have also proven ideal for low void, multiple ply lay ups. A wide variety of cure cycles, cure temperatures and pressure also allow for LC-E334 to be very user friendly throughout processing.
Physical Properties

Shelf Life / Out Life / Storage
Shelf Life: 6 months from Certification Date
Out Life: 14 days @ 70⁰F (21⁰C)

Processing/Cure Cycle Recommendations
LC-E334 can be processed at 350⁰F. (177⁰C.) for 60 minutes followed up with post cure of up to 400⁰F (204⁰ C) when a higher Tg is required. A 350⁰F (177⁰C) cure for 60 minutes is optimal in most cases using press, vacuum bag or autoclave processing with 25 psi pressure.
