  • Patent number: 10131800
    Abstract: The present invention relates to a thermosetting intumescent coating composition which is suitable for protecting substrates against hydrocarbon fires, for example jet fires. The coating composition can be used without a supporting mesh. The present invention also relates to substrates coated with the intumescent coating composition, and a method of protecting structures from fire.
    Type: Grant

  • Patent number: 10113071
    Abstract: A liquid intumescent coating composition comprising the following components: (a) 25.0-75.0 volume % of one or more organic thermosetting polymer(s) and one or more curing agent(s) for the organic thermosetting polymer(s), (b) 1.0-70.0 volume % of a source of phosphoric or sulphonic acid, (c) 6.0-60.0 volume % of a source of boric acid, (d) 0-2.0 volume % of melamine or melamine derivatives, (e) 0-1.0 volume % of one or more isocyanurate derivatives, wherein the volume % of components (a), (b), (c), (d) and (e) is calculated on the total volume of the non volatile components in the coating composition. The thermosetting intumescent coating composition is suitable for protecting substrates against hydrocarbon fires, for example jet fires. The coating composition can be used without a supporting mesh. The present invention also relates to substrates coated the intumescent coating composition, and a method of protecting structures from fire.

  • Patent number: 8357728
    Abstract: The present invention relates to a method for producing a porous material comprising the steps of; (a) providing a C/W emulsion comprising an aqueous phase, a matrix building material, a surfactant and liquid CO2 phase; (b) at least partially freezing the aqueous phase; (c) gasifying CO2 from the liquid CO2 phase to form an intermediate porous material; (d) venting gasified CO2 from the intermediate porous material; and (e) freeze drying the intermediate porous material at least substantially to remove the aqueous phase and form the porous material. The present invention also relates to a porous material obtainable by the method.
