United States Gypsum Company offers a full line of HYDROCAL™ Brand Gypsum Cements that possess greater strength and hardness than standard industrial plasters. HYDROCAL™ Brand Gypsum Cements require less water for mixing, producing casts that are less porous, easier to paint, heavier, and more durable. Medium High-Expansion HYDROCAL™ Cement is a specially formulated gypsum cement having unique characteristics. This material expands uniformly in all directions and compensates for metal shrinkage during metal casting. Expansion values can be controlled by the quantity of water used in the mix.

HYDROCAL™ Gypsum Cement products from United States Gypsum Company's Industrial Products Division are available in several grades, specially formulated for specific applications. HYDROCAL™ Brand Gypsum Cements possess greater strength and hardness than standard industrial plasters or plaster of paris.
