On the role and transformations of components of intumescent fire-retardant paint-and-varnish formulations in the course of thermolysis

Main components of fire-retardant intumescent paint-and-varnish formulations, such as pentaerythritol, melamine, and ammonium phosphate, were considered in detail. A comprehensive thermal study of these components was carried out, including thermogravimetric and differential thermal analyses. A mechanism of transformations of these substances in the course of thermal degradation is described.
