ULTRACAL® 30 Gypsum Cement
Super-strength gypsum cement recommended where extreme accuracy and greater surface hardness are required, as in duplicator models. Harder and stronger than HYDROCAL® A-11 and HYDROCAL® B-11 cements, ULTRACAL® 30 cement has the lowest expansion of any rapid-setting gypsum cement available. Has a gradual set and long period of plasticity.
Ideal for splash-casting molds and models for phenolic, polyester and epoxy resins. It was designed to give the pattern making industry the ultimate in a gypsum cement-tooling medium.
