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.

Ideal material for silicone mold making.
