Whip Mix ResinRock ISO Type 4 Die Stone Golden Brown 55 lb / 25 kg (MPN 34985)

Whip Mix ResinRock is an ISO Type 4 die stone combining synthetic resin with alpha gypsum to deliver enhanced surface smoothness, abrasion resistance, and dimensional stability with a setting expansion of just 0.08%. These properties make it well suited for implant and complex restorative cases requiring a high degree of precision. The golden brown color provides strong contrast against casting waxes and produces scannable models compatible with CAD/CAM systems, eliminating the need for a separate scan stone or spray coating. Compressive strength reaches 7,000 psi wet at one hour and 11,000 psi dry at 48 hours, with a working time of 5–7 minutes and a setting time of approximately 10 minutes at a water-to-powder ratio of 20 mL per 100 g. Gypsum Hardener is not recommended for use with this product. This package contains 25 kg (55 lb) of powder.
