More about Epoxy Thin-Film Intumescent Coating

Epoxy thin-film intumescent coatings are two-part systems mixed on site and applied to steel to provide intumescent passive fire protection. Coatings rely on intumescent systems comprised of a carbon-containing charring component, a phosphorous-containing component, and a melamine blowing agent. In the event of fire, the intumescent system reacts to expand and form an insulating barrier around the steel substrate. Products reviewed for this CP were formulated for both hydrocarbon and/or cellulosic fires and are certified accordingly; fire rating will depend on the specific product, substrate, and application though are typically rated between 1-4 hours. Products commonly require use of an approved primer and may be optionally top-coated depending on intended use and aesthetic preferences; both are outside of the scope of this CP.
