ULTRACAL® 30 Gypsum Cement

ULTRACAL® 30 Gypsum Cement is traditional tooling gypsum cement specially formulated for close tolerance tooling. It is ideal for splash-casting molds and models for phenolic, polyester, and epoxy resins. 

It features exceptional hardness and accuracy, as well as the lowest expansion of any rapid-setting gypsum cement and is recommended where extreme accuracy and surface hardness are required, as in duplicator molds.

The plaster requires 38 parts water by weight per 100 parts plaster, and after machine mixing, it sets in 25-35 minutes.  

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