Whip Mix ResinRock ISO Type 4 Die Stone Golden Brown 33 lb / 15 kg

Whip Mix ResinRock is an ISO Type 4 die stone that combines synthetic resin with alpha gypsum to deliver superior surface smoothness and abrasion resistance compared to conventional die stones. Its low setting expansion of 0.08% and dimensional stability make it well suited for implant and complex restorative cases requiring precise fit. The golden brown color provides strong contrast to casting waxes and is compatible with CAD/CAM scanning workflows, eliminating the need for a separate scan stone or spray coating. This 33 lb (15 kg) quantity offers a water-to-powder ratio of 20 mL per 100 g, a working time of 5–7 minutes, and compressive strengths of 7,000 psi wet and 11,000 psi dry. Use of Gypsum Hardener is not recommended with this product.
