FlowStone FS

Fast-Setting Fluid Low-Expansion Base Stone

ISO Type 4

FlowStone FS sets 50% faster than typical stone products. Early high strength allows separation from base mold in 15 minutes. Use Flowstone FS with Lean Rock Die Stone and streamline your entire model fabrication process.

Flowstone FS delivers all the benefits and features of Flowstone and more:

  • Low Setting Expansion – .08% produces a dimensionally stable base for master models
  • Dense surface – Resists dowel pin abrasion
  • Quick, 8 minutes setting time – Allows for small batch processing (about 6 bases in one pour) Manual stacking is eliminated
