Forton VF-812 is a specially formulated, all acrylic co-polymer which cross-links with a dry melamine resin to make the Forton MG (Modified Gypsum Casting System) moisture resistant and UV stable. FMG is a unique combination of high-strength alpha hemi-hydrate gypsum with water based polymer chemistry that is reinforced with “E” glass fiber. FMG is the first technology to make gypsum an exterior product, when painted or sealed, and is certified as meeting the ASTM E-84, Class A (or 1) flame rating for building materials. Forton MG can be used for restoration and replication of natural façade materials, architectural ornamentation, decorative arts casting, flower pots and cold cast metal elements and sculpture.
