Offering extreme accuracy, it is specifically designed for making die-sinking patterns by the splash-cast technique and original loft template models. USG Hydrocal B-11 is a gray gypsum cement that sets in about 30 minutes after mixing, providing ample time for build-up work. In addition, it is water soluble; there is no need for organic solvents for cleanup.
