Description
LC-E328 is a single or two side coated, epoxy glass prepreg designed for service temperatures at 350⁰F (176⁰ C) with intermittent temperatures up to 500⁰ F (260⁰ C). This system can also be ideal for multi-ply laminates requiring thick cross sections.
Advantages
LC-E328 can be layed up and cured in thick laminates without worry of exotherm (eg., Very Hot Reaction). A wide variety of cure cycles also allow for LC-E328 to be very user friendly throughout processing. Low volatiles have proven ideal for low void, multiple ply lay ups.
