We supply a wide range of epoxy prepregs, but we can also supply both polyester and vinyl ester ones under an scheduled program. Please, ask for quotation and lead times
Advantages of Prepregs
- Perhaps the greatest advantage of using prepregs is their ease of use. An epoxy prepreg comes on a roll and has the desired amount for both resin and hardener already impregnated in the fabric. Operators are not in contact with hazardous products.
- No mixing ratio mistakes possible.
- Glass to fibre weight ratio control.
Disadvantages of Prepregs
Since the epoxy is in a B-stage, it is required to be stored either refrigerated or frozen prior to use. Additionally, the overall shelf life can be low, normally ranging from few days to a month at 23 ºC.
