Abstract
Official abstract text for this publication.
The incorporation of polyvalent metal ions into a silicate based interlayer in a laminated fire resistant glazing produced using a cast in place process provides an improvement in the properties of those glazings. The preferred metal ions are aluminium ions and zirconium ions. The preferred polyvalent metal compounds are those which are disclosed in EP 1206349 and WO 2004/014813.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for the production of a fire resistant laminated glazing comprising a silicate based interlayer which comprises pouring a solution of an alkali metal silicate into a cavity formed between two opposed transparent panes and allowing the solution to cure without drying, wherein the aforesaid solution further comprises a polyvalent metal compound and wherein the interlayer comprises between 35 and 60% by weight of water. 2. The…
