Low-Expansion Die Stone

ISO Type 4

SILKY-ROCK is characterized by exceptional hardness and density throughout, and an unusual “silky-smooth” pouring quality that makes it flow freely into any type of impression. It works well with all types of impression materials. These properties, together with its low setting expansion, make SILKY-ROCK one of the world’s most popular die materials.
