A process for applying an insulating bonded refractory fiber layer to a substrate such that the bonded refractory fiber will not delaminate form the substrate it is adhered to during thermal cycling. A pre-coat layer of refractory fiber coated with a binder containing potassium silicate, colloidal silica, kaolin clay, hydrated alumina, and optionally, Xanthan gum is applied to a substrate, preferably by spray application. Then a second insulating layer of refractory fiber coated with a binder containing either colloidal alumina, colloidal silica, colloid...
A process for producing a refractory layer on a substrate comprising in order the steps of: (a) directing a first stream of refractory fibers toward the surface of a substrate; (b) coating said first stream of refractory fibers with a liquid binder comprising about 25-35 wt% potassium silicate; 10-50 wt% colloidal silica; 4-8 wt% kaolin clay; and 2-6 wt% hydrated alumina during said step of directing such that said refractory fibers adhere to to another and to said surface; (c) directing a second stream of refractory fibers toward the refractory pre-coat...
