first dispersant 26 and the second dispersant 28 are combined to form combined silicone resin 30 use of high viscosity resin and reducing its viscosity to an optimal range by pre dispersing the two components of the resin in a specifically defined solvent at a specific blend ratio under a specifically defined method is critical in the present disclosure combined silicone resin 30 is measured to an appropriate amount for application to a fabric sheet 32 which is comprised of silica a basis weight of the fabric sheet 32 is preferably between 180 and 600 gsm the fabric sheet may be leached which is a known process in the art however the present disclosure requires identification of the appropriate starting material for the fabric sheet 32 which will allow it to be leached while maintaining the necessary strength for designated use the appropriate fabric sheet 32 is an opaque silica fabric of sufficient thickness weight and strength such that it can be leached to increase silica concentration and still remain strong enough for sufficient fire and pressure resistance and become translucent or transparent after application of a silicone resin that is refractory index ri matched to the fabric the proper amount of combined silicone resin 30 is dependent on the thickness density and size of the fabric sheet 32 the combined silicone.
