Hard Rock is High-Strength, High-Expansion Die Stone

The material is compatible with all types of impression materials. Its high expansion makes it especially suited for polyvinyl or polyether impression materials. This material has a creamy and thixotropic consistency for good flow under vibration, yet is very stackable. Its extended working time facilitates multiple pours. The stone has a smooth non-brittle surface so dies trim easily without chipping.
