    Overview

    Exceptionally strong gypsum cement designed for stretch-press dies and producing cope-and-drag equipment. *Produces high-quality, indoor novelty and statuary castings that require extremely hard surfaces and superior reproduction of fine detail. Superior expansion vs. Hydrocal® A-11 or B-11 gypsum cements. *High water absorption resistance.

    Main Features

    Hydro-Stone® Gypsum Cement is especially suitable where high strength and resistance to water absorption are necessary. It is ideal for applications in both the tooling & prototyping and art & statuary categories.
    Hydro-Stone® Gypsum Cement — For Tooling & Prototyping
    Hydro-Stone® Gypsum Cement is ideal for stretch-press dies where extreme surface hardness is required. Offering greater expansion than Hydrocal® A-11 or B-11 gypsum cements, Hydro-Stone® Gypsum Cement:
    • Features a heavy, syrupy consistency, ideal for pouring into solid models or patterns (and making it ideal for filling multiple molds simultaneously)
    • Adapts to most flexible moulding compounds, due to its high absorption resistance
    • Sets in 17-20 minutes, after machine mixing
    • Requires 32 parts water by weight per 100 parts plaster.
    NOTE — For best storage results, keep indoors in a dry, stable environment, away from drafts. Do not stack more than two pallets high.
    Hydro-Stone® Gypsum Cement — For Art & Statuary
    One of the hardest and strongest Hydrocal® products, Hydro-Stone® Gypsum Cement is used in the fabrication of high-quality art novelty and statuary castings. Offering excellent paintability, Hydro-Stone® Gypsum Cement:
    • Can duplicate extremely fine details
    • Works well in plaster and most flexible moulding compounds
    • Is self-leveling, with low viscosity
    • Provides fast set time for quick mold turns
