Influence of titanium dioxide on the performance of intumescent coatings


Monné Pompido, Alba

Titanium dioxide (TiO2) is a key ingredient that influences the properties and performance of intumescent paints. The aim of this study is to investigate the effect of different commercial brands of TiO2 in a solvent-based paint by studying 31 different TiO2 samples. The characterization of the samples has been carried out using different methods and techniques, the thermal properties have been measured by thermogravimetric analysis (TGA), the thermal insulation performance of the paints has been measured in a gas oven using an IPE160 and the ash expansion and morphology by means of panels. The results have shown that the type of glass, purity, and inorganic surface treatment of TiO2 has an influence on the performance of the paint, obtaining better results for a TiO2 of type R2 with Al or Al, Zr as inorganic treatment.
