United States Gypsum Industrial Plaster & Gypsum Cement Products

Hydrocal FGR 95 Gypsum Cement

Hydrocal FGR 95 Gypsum Cement is a unique high-strength product used with glass fibers and/or glass fiber mat for fabricating lightweight fire resistant decorated shapes, architectural elements, column covers, cornices, and trims. Adapts to most patterns, accepts most coatings. Safe and non-toxic; zero flame spread, zero smoke contribution material. In 50 and 100 lb. bags.

Hydrocal FGR Gyspum Cement from United States Gypsum Company can open the door to many three-dimensinal possibilities. A great variety of finished items, formerly made from conventional plaster, wood, concrete, sone, and other materials, can be duplicated, often at less cost using the unique properties of Hydrocal FGR Gypsum Cement.

Used for Glass-Reinforced Gypsum (GRG) fabrication, Hydrocal FGR Gypsum Cement is an alpha-hemihydrate gypsum based material that has a low water demeand. This results in high strenth, high density pieces that can be fabricated for a variety of interior architectural applications.

Hydrocal FGR Gypsum Cement sets fast, develops high strength, and permits fabrication of strong, resilient glass reinforced gypsum products. These durable products are fire resistant, are adaptable to deep patterns,  help overcome the building fire code problems of many plastics, and cost about 2/3 less than filled polyesters.

The economical price and fabrication flexibility allow you to duplicate existing pieces for renovation projects or create your own masterpieces quickly and easily.

Hydrocal FGR Gypsum Cement's features:

• Versatile - An easily decorated surface accepts most oil-base, alkyd, or latex paints, and most stains, lacquers, varnishes, or shellacs to create just the right finish for your application.

• Thin and Lightweight - 1/10 in. thick Hydrocal FGR Gypsum Cement panels weigh only 9 to 10 lb. per sq. ft., reducing the costs of reinforcing the building.

• Strong - Because Hydrocal FGR Gypsum Cement is reinforced with glass fibers it is strong and durable. Test results show a flexural strength of 4,000 psi, flexural modulus of 2.1 x 10^6 psi, and impact strength of 8.0 to 8.8 ft. lb./in.

• Fire Resistant - Laboratory fire tests conducted on varying thicknesses of Hydrocal FGR Gypsum Cement (with 5% glass fiber content and without face coating) substantiate its noncombustibility and show no appreciable fuel contribution and zero flame spread. (The tests were conducted in accordance with ASTM E136-94A "Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C")

• Easy to Install - Hydrocall FGR Gypsum Cement can be precast off-site allowing less work in the field and reduction of on-site costs.
