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)

Cure Cycle and Tg
105~115°C achieved after 240min curing @ 90°C
120~130°C achieved after 40min curing @ 130°C
120~130°C achieved after 10min curing @ 150°C
Out of autoclave curing
Vacuum shouldn't not be less than -0.085Mpa and rate of heating should be 1-3°C/minute. For ideal curing, hold for 60 minutes at 130°C. Avoid rapid cooling.
Autoclave Curing
Vacuum shouldn't not be less than -0.085Mpa, pressure should be 1-3 bar and rate of heating should be 1-3°C/minute. For ideal curing, hold for 60 minutes at 130°C. Avoid rapid cooling.
