摘要： The present invention relates to a fire resistant glazing unit (10), and in particular to novel curable gelling compositions which may form a fire-resistant hydrogel interlayer (3) between the glass panes (1) of the glazing unit (10). The gelling compositions of the invention are generally obtained by mixing together a curable hydrogel-forming component; one or more salts (suitably selected from metal(I) and/or metal(II) salts); a gel stabilising agent; and an aqueous vehicle; wherein the gel stabilising agent is (or comprises) a compound having a multivalent central atom with an atomic number greater than or equal to 13; wherein the composition has an acidic pH wherein the pH is greater than or equal to pH 3. Such gelling compositions, when cured to form a hydrogel interlayer, provide excellent fire-resistant properties and also an excellent radiation barrier in the event of a fire. Moreover, cured gelling compositions of the invention are also extremely stable over prolonged time periods over a range of temperatures.
