Description
ULTRACAL 30 was designed to give the pattern making industry the ultimate in a gypsum cement-tooling medium.
ULTRACAL 30 Gypsum Cement is a super-strength gypsum cement recommended where extreme accuracy and greater surface hardness are required, as in duplicator models. 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.
