Whip Mix Hard Rock Green ISO Type 5 Dental Die Stone 33 lb / 15 kg

Whip Mix Hard Rock Green is an ISO Type 5 dental die stone supplied in a 33 lb (15 kg) quantity, compatible with all impression material types including polyvinyl and polyether. Its higher setting expansion of 0.28% makes it particularly well suited for use with dimensionally stable elastomeric impression materials. The creamy, thixotropic consistency flows readily under vibration while remaining stackable, and a working time of 6 to 8 minutes allows for multiple pours from a single mix. The material sets in approximately 15 minutes and produces a smooth, non-brittle surface that trims cleanly without chipping, achieving a wet compressive strength of 7,000 psi at one hour and a dry compressive strength of 15,000 psi (104 MPa) at 48 hours.
