Gray MatterŪ: the intelligent shell system

Gray Matter is an innovative composite shell system designed to include a colloidal silica binder, polymer and a pre-blended refractory package:

  • Ready-to-use components to simplify the slurry making process
  • A strong laminated shell to withstand handling abuse and autoclave cracking
  • Excellent rheology to build a uniform shell, even on sharp edges and corners
  • Shell thickness and load-bearing capability you need in fewer coats, reducing material consumption and production time per shell
