<p>A flexible, fire-retardant, intumescent composition comprising: (a) an intumescent material; (b) an effective amount of a stabilizing agent, and (c) an organic binder throughout which the intumescent material and stabilizing agent are dispersed, the elastomeric binder being at least partially crosslinked, wherein the stabilizing agent consists essentially of a compound selected from the group consisting of compounds within general formula (I) wherein R1-R4 inclusive are independently selected from the group consisting of hydrogen and alkyl groups having from 1 to about 5 carbon atoms, with the provisos that: (i) either both of R?1 and R2¿, or both R?3 and R4¿ are alkyl groups having from 1 to about 5 carbon atoms; and (ii) the stabilizing agent has a melting point ranging from about 105 °C to about 125 °C.</p> |
