PRO-SET^® Laminating Epoxies

Fire Retardant laminating resin is now available as Special Order Formulation.

Vacuum Bagging Lamination

Vacuum bagging is an excellent clamping method for composite construction using PRO-SET^® Epoxies. Regulating the amount of vacuum pressure permits control of the resin/fibre ratio and can produce a denser laminate, with a higher fibre volume. Generally, the higher the vacuum pressure, the lower the resin content. The optimum resin/fibre ratio for a particular component will be between 30% and 50%. A lower ratio will result in a lighter composite. A higher ratio will be heavier yet yield higher moisture exclusion effectiveness. Various bleeder and absorber materials used in vacuum bag laminating can also influence the resin/fibre ratio. Building test panels is recommended to determine the proper vacuum bagging material schedule and vacuum pressure for a particular component.
