[0093] figure 2 The illustrated method of making laminated glass may further include, before or during the step of curing the silicone resin, compressing the assembly to remove excess composition and / or entrapped air and reduce the thickness of the laminated glass. The assembly can be compressed using conventional equipment, such as stainless steel rolls, hydraulic presses, rubber rolls, or laminated roll arrangements. Typically the assembly can be compressed at a pressure of 1000 Pa - 10 MPa.

[0094] Alternatively, a first polysilicate coating can be formed by (i) forming a first polysilicate coating on a first glass sheet, (ii) forming a second polysilicate coating on a second glass sheet, (iii) forming a coating on the first polysilicate Applying the above-mentioned curable silicone composition containing silicone resin on the coating to form a first silicone adhesive film, (iv) impregnating fiber reinforcement in the first silicone adhesive film agent, (v) placing a se...

[0108] The reinforced silicone resin films of Examples 4, 5 and 6 were prepared according to the following procedure: Silicone Composition A was applied to A silicone film was formed on the release agent treated surface of 516 PET film (8 inches x 11 inches). Carefully spread a glass fabric of the same dimensions as the PET film on the silicone film, allowing sufficient time for the composition to wet the fabric thoroughly. The aforementioned silicone composition is then applied uniformly to the embedded fabric. The same PET film was placed over the coating with the release agent treated side in contact with the silicone composition. The laminate was heated in a 150°C oven for 30 minutes. The oven was turned off and the laminate was allowed to cool to room temperature inside the oven. The upper PET film was separated (peeled off) from the reinforced silicone resin film, and then the silicone resin film was separated from the lower PET film. The transparent reinforced sili...

Embodiment 2

[0111] Flotation glass plates (6 inches x 6 inches x 1 / 8 inches) were washed with a hot solution of detergent in water, rinsed thoroughly with deionized water, and air dried. Using masking tape, edge baffles were constructed around the perimeter of each glass sheet. Will about 45ml RR sodium silicate solution was applied to one side of each glass plate. The coated glass plates were kept in a sealed glass chamber containing saturated calcium nitrate solution at a relative humidity of 51% for 76 hours. The water content of the polysilicate coating on each glass plate was 32-35% (w / w).
