ABSTRACT:
Intumescent coatings protect structural members from exceedingly high temperatures during fires. Most intumescents, in their virgin condition, can be made to bond tenaciously to the substrate surface it is to protect. When activated by a fire, intumescent materials swell and undergo chemical degradation, and in the process a char is produced. The char insulates the substrate from the heat flux (fire). A reticulated structure is provided to anchor the char to the substrate.
