USG Ultracal® 30 Gypsum Cement is a traditional tooling gypsum cement, specially formulated for close tolerance tooling. Is recommended where extreme accuracy and surface hardness are required (i.e. duplicator molds)

  • Provides the lowest expansion of any rapid-setting gypsum cement
  • Is ideal for splash-casting molds and models for phenolic, polyester and epoxy resins
  • Sets 25-35 minutes after machine mixing
  • It has a gradual set and long period of plasticity.
  • It is harder and stronger than HYDROCAL A-11 and HYDROCAL B-11 cements.

Requires 38 parts water by weight per 100 parts plaster

NOTE - For best storage results, keep indoors in a dry, stable environment, away from drafts. Do not stack more than two pallets high.
