Specialty Stone Mounting Stone Whip Mix Gypsum


ISO Type 3

Low expansion, fast setting stone gypsum

Available in Blue and White

SKU: N/A Category: Tag:


A very hard, fast setting gypsum material formulated expressly for mounting casts to articulators. Its very low setting expansion prevents inaccuracies in occlusal cast relationships that result when conventional model stone or plaster is used. Although Mounting Stone has excellent stacking qualities, it moves very freely under the slightest pressure during its working time. It can be used as a model stone when a rapid set is required.
