HB20 is designed specifically for use in high temperature vacuum-formed fibrous refractories. It provides a good balance of particle size, concentration and pH to enhance the binding characteristics while optimizing the economics of the binder system. HB20 is effective in high-temperature refractories as a stable binder where colloidal silica binders fail. Its other uses are as a catalyst support/binder and as a ceramic binder. HB20DW is made by custom order with deionized water to reduce the sodium and chlorine levels to less than 10 ppm.
