USG Gypsum & Plaster

Reynolds Advanced Materials carries a wide variety of USG Gypsum products. This selection of gypsum plasters is suitable for a number of mold making and casting applications ranging from giftware and sculpture casting, to industrial and production applications.

 No. 1 Casting Plaster
The industry standard for figurines, plaques, and lamp bases. Special additives maintain smooth-working qualities and upon drying, result in a hard working surface with reduced paint absorption and degree of chip-resistance.

No. 1 Pottery Plaster
USG No. 1 Pottery Plaster is noted for outstanding performance and long life. The standard of the industry, it is the best material available for sanitary-ware and dinnerware slip casting. 

Hydro-Stone® Gypsum
HYDRO-STONE® is recommended for producing high-quality novelty and statuary castings requiring extremely hard surfaces. This product is self-leveling when poured and not suitable for hollow cast applications.

Snowwhite Filler Gypsum
Its bright white color, softness, and good acid resistance provides a superior medium as a functional filler in polymers, caulks, and adhesives.  Its whiteness, softness, acid resistance and binder carrying ability makes it a good candidate for use in adhesives and caulks.

Hydrocal® FGR-95 Gypsum
Hydrocal® FGR-95 Gypsum Cement is specially formulated to set fast, develop high strength, and permit fabrication of strong, resilient glass-reinforced products. The superior fire retardant properties allow for safe, code-compliant installation in all types of public and private structures.

Hydrocal® White Gypsum
A good general use product recommended for solid and hollow casting of lamp bases and figurines. Designed for thin sections which require high green strength to minimize breakage.

UltraCal® 30 Gypsum
A super-strength gypsum cement that has the lowest expansion of any rapid-setting gypsum cement available. Ideal for splash-casting molds and models for phenolic, polyester and epoxy resins.

No. 1 Molding Gypsum
Often referred to as “plaster of Paris” or soft plaster. Used for waste molds or temporary patterns where surface hardness and strength are not important.
