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 […]

The optimal thickness of intumescent coating depends on the material being protected, the required fire-resistance rating, and the product’s tested performance characteristics. Standard application thicknesses range from 0.5 mm to over 5 mm (20 to 200 mils), with structural steel often requiring between 1.5 mm and 3.5 mm for 60- to 120-minute ratings. For non-structural […]
