Features & Benefits

You can use our prepregs any number of ways including, but not limited to, autoclave, press, vacuum, and compaction tapes. Since most shops do not have access to an autoclave or heated press, the latter two options are mostly used for smaller operations. This Prepreg material is ideal for use as an isolative inner or outer ply on any project helping to prevent galvanic corrosion. 

 

Prepregs have special policies related to returns and shipping. Please review them here prior to order.
