Abstract:
    A process is disclosed for providing a refractory composition on a surface. In the process an acidic hybrid binder composition and a basic colloidal silica sol composition are provided. The surface is coated with the acidic hybrid binder composition and the colloidal silica sol composition so that each colloidal silica sol composition coat contacts an acidic hybrid binder composition coat to form alternating layers of the acidic hybrid binder composition and the colloidal silica sol composition. Each acidic hybrid binder composition layer and each colloidal silica sol layer are dried prior to coating with the alternating layer to a sufficient hardness such that lift-off of the applied coatings from the surface is inhibited when a subsequent coating step is performed. A refractory laminate composition is also disclosed which comprises a plurality of layers of hardened acidic hybrid binder composition alternating with a plurality of layers of hardened basic colloidal silica sol composition.
