NYACOL COLLOIDAL ALUMINA

High Temperature Coating/Binder

Nyacol AL20 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.  Nyacol AL20 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.  Nyacol AL20DW is made by custom order with deionized water to reduce the sodium and chlorine levels to less than 10 ppm.
