Zoho Stone HybriCast™ Forton® MG (Modified Gypsum)



In 1990, the Forton® Modified Gypsum Casting System (HybriCast™ FMG) was introduced into the global market as an alternative light weight architectural precast to regular heavy concrete. or GFRC. HybriCast™ FMG is an ultra strong, ultra light, weatherproof, odorless, and most importantly, non toxic and non porous material casting system that can be sculpted like plaster. FMG consists of a gypsum plaster modified (Modified Gypsum) by the addition of fiber-glass. The system involves mixing precise amounts of several products, including Hydrocal FGR-95 from US Gypsum (gypsum-based cements), dry melamine resin powder, a hardener, a liquid polymer called Forton® VF-812 and glass fibers. These various ingredients are the base to which aggregates, colorants and metallic powders may be added.

Applications for HybriCast™ FMG includes solid or hollow casting of architectural ornaments, replication of natural materials for restoration, custom decorative art, and cold cast metal.
