Which type of failure describes a separation within SFRM?

Separation within the sprayed fireproofing material means the fracture occurs inside the coating itself, not at the bond with the substrate. That internal failure of the coating is cohesive failure—the material’s own internal strength is exceeded, causing cracks or splits within the layer while the coating may still be attached to the surface. This is different from adhesive failure, where the split happens at the interface between the coating and the substrate. Thermal or mechanical failures describe damage from heat or external forces, but not the internal split within the coating. So the described type of failure matches cohesive failure.
