摘要：A process for applying an insulating bonded refractory fiber layer to a

substrate such that the bonded refractory fiber will not delaminate from 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, Xantham 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, colloidal zirconia, aluminum phosphates, or mixtures

thereof is applied to the pre-coated substrate, preferably by spray application. Finally,

the coated layers of bonded refractory fibers are cured. An article comprising a

refractory layer bonded to a substrate produced by the foregoing process is also

disclosed.
