摘要： This specification generally relates to aqueous compositions for preparing UV stable fire-resistant interlayers. It also relates to UV stable fire-resistant glazing laminates comprising such interlayers, the use of such glazing laminates in construction, and constructions comprising such glazings. An example aqueous composition comprises a mixed alkali metal silicate of general formula SiO2.M2O, where M is K or Na, and other organic and inorganic additives. Glazings with interlayers made with such aqueous compositions are simple to prepare and demonstrate good UV stability and fire-protection properties.
