Classification: CPC C  A  B | IPC A  C

Claim 0:
1. A flame retardant product intended to be diluted and consisting of an aqueous solution comprising:
a hydroxylated carbon-based component,
an intumescent agent suitable for at least partially or even completely dehydrating the hydroxylated carbon-based component in such a way as to generate, under the effect of heat, a carbonaceous foam,
between 5% and 20% by weight of a thixotropic agent, selected to have a viscosity that increases as a result of water being added in the absence of shear,, the solution having a sufficient concentration of the hydroxylated carbon-based component and the intumescent agent so that an addition of water to said solution increases the viscosity thereof in the absence of shear, and so that shear applied to the corresponding diluted solution decreases the viscosity thereof,, the content by weight of the hydroxylated carbon-based component being greater than 12.5%,, the flame retardant product being obtained by a method comprising the following successive steps:, a) preparation of a composition comprising the intumescent agent the hydroxylated carbon-based component and water, the total content by weight of the hydroxylated carbon-based component and of the intumescent agent in the composition being greater than 95% of the saturation weight content at which saturation is reached,, b) mixing of the thixotropic agent with the composition such as to obtain the aqueous solution.
