ULTRACAL 30 GYPSUM CEMENT: Superior tooling gypsum cement features exceptional strength and hardness. Low-absorption, designed for use in case molds.MAIN FEATURES
Ultracal 30 Gypsum Cementis a traditional tooling gypsum cement, specially formulated for close tolerance tooling. Low absorption Ultracal® 30 Gypsum Cement:
NOTE - For best storage results, keep indoors in a dry, stable environment, away from drafts. Do not stack more than two pallets high.
Ultracal 30 Gypsum Cementis a traditional tooling gypsum cement, specially formulated for close tolerance tooling. Low absorption Ultracal® 30 Gypsum Cement:
- 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
- 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.

HYDROCAL B11: High-strength gypsum cement features a low setting expansion, high degree of plasticity and gradual setting action. Designed for producing original loft template models and die-sinking patterns by the splash-cast technique.MAIN FEATURES
Hydrocal B-11 Gypsum Cementgypsum cement is a high-strength gypsum cement designed for tooling applications. The plaster is similar to Hydrocal A-11 Gypsum Cement in setting expansion and accuracy, but not quite as strong. Hydrocal B-11 Gypsum Cement:
NOTE - For best storage results, keep indoors in a dry, stable environment, away from drafts. Do not stack more than two pallets high
Hydrocal B-11 Gypsum Cementgypsum cement is a high-strength gypsum cement designed for tooling applications. The plaster is similar to Hydrocal A-11 Gypsum Cement in setting expansion and accuracy, but not quite as strong. Hydrocal B-11 Gypsum Cement:
- Features a longer period of plasticity, enabling it to be used with templates to screed models directly from gypsum
- Offers a low setting expansion, high degree of plasticity and gradual setting action
- Sets 25-35 minutes after machine mixing
- Requires 44 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

HYDROCAL WHITE: Multi-purpose gypsum cement ideal for both solid and hollow casting of lamp bases and figurines. High green strength minimizes breakage during removal from the most intricate latex molds.MAIN FEATURES
Offering twice the compressive strength of plaster, Hydrocal White Gypsum Cement is especially suitable in thin, delicate sections where high green strength is required. Multi-purpose Hydrocal White Gypsum Cement:
Offering twice the compressive strength of plaster, Hydrocal White Gypsum Cement is especially suitable in thin, delicate sections where high green strength is required. Multi-purpose Hydrocal White Gypsum Cement:
- Is ideal for both solid and hollow casting of lamp bases, figurines, moldings and general castings
- Offers long workability; setting expansion twice that of molding plaster and pottery plaster
- Has a great value to performance ratio
- Achieves a stark, white color, making it ideal for accepting colorants
- Sets 25-35 minutes after machine mixing
- Requires 45 parts water by weight per 100 parts plaster.
