Forton MG or FMG is a four component system which consists of an alpha gypsum blended with three specialty additives. FMG is based on the VF-812 water based polymer emulsion (50% solids) and greatly enhances the physical properties of alpha gypsum products. VF-812 drastically reduces water permeability, making it suitable for both interior and exterior applications (for exterior use, product must be sealed – see “Finishing” section).
The Forton MG system is easy to use and can be cast solid, rotationally cast, layed up by hand with glass fiber or sprayed. Fully cured pieces can be painted, sanded, machined and polished. FMG is used to make lightweight pieces that are very strong and water-resistant. Applications include making architectural elements, reproducing sculpture and special effects.
