Abstract: The invention relates to a composite material comprising at least two substrates onto which a layer of an intumescent composition is set therebetween, said composition comprising a mixture of following individual constituents: from 5 weight % to 70 wt% of at least one carbon source, from 0 weight % to 50 wt% of at least one acid source, and from 5 weight % to 50 wt% of least one expanding agent, the total being 100 wt%, wherein the intumescent composition is active at an intumescent predetermined temperature of from 120°C to 450°C, said intumescent temperature being less than the degradation temperature of said at least two substrates. The invention also relates to use of said intumescent composition for disassembling, at an intumescent predetermined temperature of from 120°C to 450°C, a composite material comprising at least two substrates onto which a layer of said intumescent composition is set therebetween.
