Intumescent coatings are paint-like products that swell into an insulating char when fire heats them. That char slows the heat reaching the steel, wood, or foam underneath. They don’t stop a fire. They buy time for people to get out and for the structure to hold up. How Do Intumescent Coatings Work? The coating sits […]
The thickness of intumescent paint required for maximum fire resistance depends on several interrelated factors, including the substrate type (steel, wood, or gypsum), the steel section’s weight-to-heated-perimeter ratio (W/D), the desired fire-resistance rating (typically 60 to 180 minutes), and the specific product’s tested performance data per ANSI/UL 263 and ASTM E119 standards. There is no […]
Choosing between intumescent coatings vs fire retardant paint comes down to one question: does the surface need a thermal barrier, or does it just need to resist flame spread? The two are often used interchangeably in conversation, but they behave very differently once heat is applied, and code requirements usually dictate which one a project […]
For a 2-hour fire-resistance rating, intumescent coating thickness for a 2 hour fire rating typically falls between 3.5 mm and 5.0+ mm (140 to 200+ mils) of dry film thickness on structural steel, though the exact figure depends on the steel member’s size and shape and the manufacturer’s UL-tested design. For a comprehensive overview of […]
