Abstract: Intumescent paints protect steel structures from fires by creating insulative foams when heated above a critical temperature. This paper examines the fire resistance capabilities of phenyl silicone coatings in comparison to intumescent paints. A thermal constant analyzer measured the thermal conductivity of the silicone-based coatings using the transient plane source (TPS) technique. Results showed that the silicone/modifier coating consistently had lower thermal conductivities than the silicone coating. At heightened temperatures, the modifier created a thick insulative barrier which provided fire protection that was comparable to commercial intumescent paints.
