Prepreg Film Adhesive

Prepreg film adhesive for building sandwich structures Prepreg film adhesive, also known as Glue Film, is used in bonding a core material such as Nomex and Kevlar honeycomb with the surface laminate such as carbon fiber. These are extremely strong epoxy-based adhesives and fully compatible for use with our prepregs (autoclave and out of autoclave)
