High-strength gypsum cement features a low setting expansion, high-degree of plasticity and gradual setting action. Designed for producing original loft template models and die-sinking patterns by the splash-cast technique. HYDROCAL® B-11® Gypsum Cement gypsum cement is a high-strength gypsum cement designed for tooling applications. The plaster is similar to HYDROCAL® A-11® Gypsum Cement in setting expansion and accuracy, but not quite as strong.
