Available 10 lb and 50 lb boxes
Ultracal 30
High tech plaster with low expansion rate and high dimensional accuracy for tooling applications. Use to produce molds for foam latex and PVC part production, and for dimensionally stable castings. Work time is 25-35 minutes. Mix Ratio: 38 parts water to 100 parts plaster.
Available 10 lb and 50 lb boxes
CastShell Plaster
Developed to assist mold-makers when making plaster mother-mold support shells. It offers improved flow control and low sag, allowing for better vertical application. Add Hemp Fiber to lighten and strengthen support shell. Material has 10-15 minute work time and cures within 30 minutes.
