Phosphorous-based intumescent coatings : The fundamental role of these systems concerning fire-proofing treatment

The objective of this paper was to study the influence of some formulation variables of phosphorous-based intumescent coatings, formulated and manufactured for this experiment, on fire-retardant properties. Chlorinated rubber coatings based on ammonium polyphosphate, pentaerythritol, melamine, chlorinated paraffin and an endothermic filler showed very high performance after ageing. The performance of any intumescent coating depends on the ability to maintain their physical properties during exposure to humidity or water.
