  • Method for manufacturing a fire retardant composite and composite thus obtained
    Patent number: 7998570
    Abstract: The present invention relates to a method of manufacturing a fire retardant composite, a composite of a foamed polymer having a coating with fire retardant properties, and also the use of such composites. The method according to the present invention comprises the following steps: i) providing beads of foamed polymer, ii) applying a coating on the beads of step i) and iii) shaping the thus coated beads into said composite.

  • AQUEOUS COMPOSITIONS, PRECURSOR SYSTEMS AND APPLICATION SYSTEMS
    Publication number: 20100143725
    Abstract: An aqueous gel-forming composition, e.g. a fire retardant coating composition, comprises an aluminosilicate, the aluminosilicate comprising alkali metal aluminate and an alkali metal silicate, and an organic liquid having a boiling point greater than 11O° C., e.g. silicone oil. The molar ratio of SiO2:X2O for the alkali metal silicate is from 3.6:1 to 10:1, where X represents the alkali metal of the alkali metal silicate, when the alkali metal aluminate has a molar ratio of Y2O:AI2O3 of 1.35:1, where Y represents the alkali metal of the alkali metal aluminate, this providing improved water resistance for films or coatings prepared from the compositions by drying and curing.

  • METHOD OF MANUFACTURING A FIRE RETARDANT COMPOSITE, A COMPOSITE AND ITS USE
    Publication number: 20100018142
    Abstract: A method of manufacturing a fire retardant composite, a composite and its use. A method of manufacturing a fire retardant composite by applying an aqueous gel-forming composition, e.g. a fire retardant coating composition, on a substrate comprises an aluminosilicate, the aluminosilicate comprising alkali metal aluminate and an alkali metal silicate, and an organic liquid having a boiling point greater than 110° C., e.g. silicone oil. The molar ratio of SiO2:X2O for the alkali metal silicate is from 3.6:1 to 10:1, where X represents the alkali metal of the alkali metal silicate, when the alkali metal aluminate has a molar ratio of Y2O:AI2O3 of 1.35:1, where Y represents the alkali metal of the alkali metal aluminate, this providing improved water resistance for films or coatings prepared from the compositions by drying and curing.

  • Aqueous Aluminosilicate Gel-Forming Composition
    Publication number: 20090000518
    Abstract: An aqueous gel-forming composition, e.g. a fire retardant coating composition, comprises an aluminosilicate and an organic liquid having a boiling point greater than 110° C., e.g. silicone oil, which enhances the integrity of films formed by application of the composition as a coating to a surface then followed by drying.
