Hydrocal® FGR 95 is high-strength gypsum cement specially formulated for use with glass fiber for fabricating glass-reinforced architectural details. Low water requirements result in high-strength, high-density glass fiber-reinforced gypsum pieces. Ideal for producing lightweight, thin-cast, fire-resistant architectural casts, and offers superior fabrication flexibility. USG Hydrocal FGR 95 is exceptionally quick setting and accepts most coatings and finishes. USG Hydrocal FGR 95 overcomes building fire code incompatibilities faced by many plastics – at roughly one-third the cost of filled polyesters.
