Low-absorption gypsum cement offers longer set time – ideal for larger molds.
Ultracal 30 Gypsum Cement is a super-strength gypsum cement recommended where extreme accuracy and greater surface hardness are required, as in duplicator models.
It has the lowest expansion of any rapid setting gypsum cement available. It 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.
