<p>PRODUCT AND METHOD FOR. FORMING IN SITU INSOLUBLE METAL SILICATES IN WOOD PORES FOR FIRE RETARDATION AND PRESERVATION A method for fire retarding and preserving wood products, paper, cardboard, boxboard, cloth and other porous materials, having a plurality of internal voids, in which a water soluble silicate composition is applied to those porous materials, penetrating into the voids, and the material dried. Thereafter, a water soluble metallic salt composition is applied, also penetrating into the voids and reacting in situ to form a water insoluble metallic silicate with a high degree of water of hydration disposed throughout the voids.</p> |
