  • Patent number: 9789667
    Abstract: Fire resistant glazings comprise a fire resistant interlayer based upon a silicate waterglass are characterized by the incorporation of aluminum ions. The aluminate is incorporated as a solution which has been partially neutralized using hydroxycarboxylic acid which is preferably citric acid. The incorporation of aluminum provides glazings have improved fire resistance and impact properties.

  • Publication number: 20120292824
    Abstract: Bilayer materials are produced by drying a solution of an alkali metal silicate upon the surface of a flexible backing material until a flexible silicate film is produced. The film may be separated from the backing material and incorporated into laminated fire resistant glazings. The alkali metal silicate solution preferably comprise a surfactant. The bilayers may be transported or stored before the flexible silicate film is separated and incorporated into a glazing.
