Abstract
During the application of heat the intumescent coating is transformed into a swollen char material, which acts as a thermal barrier to eliminate or minimize incoming heat flux. It also acts as a mass transfer barrier, inhibiting oxygen from reaching the thermally insulative ablative material. During the intumescence process, the swollen material will also back fill into interstices within the ablative material and char to enhance their strength. The intumescent coating also acts as a moisture barrier to protect the thermally insulative ablative material from ambient elements such as moisture.
