Description

Our Fiberglass Room Temperature Prepreg is an 8.8 oz 8 Harness Satin Weave E-Glass fabric impregnated with a thermosetting epoxy resin system. It can be stored at room temperatures and does not require freezer storage. With the long out life of the resin matrix, the fiberglass prepreg can be shipped and processed at room temperatures. It is ideal for use when a long shelf life is desired, high-temperature capabilities are not required and controlled resin content is wanted.

The 8 Harness is a highly pliable fabric is ideal for applications with compound curves. The unique epoxy resin system allows for various flexible cure cycles and has a long out-life.

Please allow extra order processing time when order prepreg fabrics.
