Whip Mix Hard Rock Green ISO Type 5 Die Stone 120 x 70g Bags

Whip Mix Hard Rock Green is an ISO Type 5 die stone compatible with all impression materials, with its high setting expansion of 0.28% making it particularly well suited for use with polyvinyl and polyether impressions. The material features a creamy, thixotropic consistency that flows readily under vibration while remaining stackable, and its working time of 6 to 8 minutes accommodates multiple pours from a single mix. A setting time of 15 minutes yields a smooth, non-brittle surface that trims cleanly without chipping. Compressive strength reaches 7,000 psi wet at one hour and 15,000 psi dry at 48 hours. This package contains 120 individual 70 g bags with a recommended water-to-powder ratio of 21 mL per 100 g.
