“…the black and compact char structure slowing changes into a white brittle dusty foam at the exposed surface. The classification of stages and zones and their respective threshold temperature have been reported to occur within a range of temperatures (Figure 3), influenced by variation in coatings formulations and fire testing procedures adopted by different researchers [19,33,35,36,[38][39][40][41][42][43][44][45][46][47][48]. The evolution of the four stages is strongly dependent on the composition of the chemicals and their mixture.…”

The mainstream use of intumescent coatings for the design of fire safe steel structures has fostered extensive research into the development of effective intumescent coatings and the assessment of their fire performance as thermal barrier to structural elements and materials. The research community has highlighted numerous challenges related to the current design framework based on standard fire resistance furnace testing and the current methodologies have been questioned due to its over-simplifications, limitations and uncertainties. In order to overcome these challenges, numerous research studies have proposed comprehensive approaches and methodologies to investigate the effectiveness of intumescent coatings exposed to a range of heating and fire conditions. This review covers the more recent developments in the field of fire testing and analysis of the fire performance of steel elements protected with intumescent coatings. Apart from the chemical formulation, the substrate boundary conditions, the applied coating thickness, the heating conditions and the fire test method appeared to be the key governing factors. All of them should be considered for a rigorous and systematic testing and design environment that allows the explicit quantification of the effectiveness of intumescent coatings.

“…On the whole, the listed physical and chemical characteristics allow to obtain a quality, defect-free, durable flame retardant coating. One of the important aspects of intumescent coating is its relative water solubility [29]. Thus, when using a surface exposed to water or a humid environment, the effectiveness of base protection is reduced due to the possible washout of the compounds responsible for bloating.…”

Most structures in the Arctic and Antarctic for oil and gas production are offshore stations, tankers, modules, steel supporting, and enclosing structures, which need to be protected against both cryogenic spills and fire exposure. Oil and gas industry facilities have products of high flammability and explosiveness, which in the case of ignition make it possible to develop a fire along the hydrocarbon curve, accompanied by a sharp jump in temperature and the formation of excessive pressure. This article discusses possible structural fire protection for metal structures in the Arctic region. Three different structural fireproofing materials are presented using super-thin basalt fiber (STBF) as an example. Tests of steel structures with fire protection are demonstrated, as a result of which the time from the beginning of cryogenic exposure to the limit state of samples is determined, and after the time from the beginning of thermal exposure to the limit state of samples under the hydrocarbon temperature regime is determined. An assessment of various flame retardants with values up to 120 min, which can be used in arctic climate conditions, was carried out. It was found that the most effective coatings are materials prepared on the basis of STBF.

“…The ingredients of the compositions are classified in accordance with the functional contribution of each of them to the process of thermolytic synthesis of fire-retardant coatings. The ingredients include donors of acid (ammonium phosphates), coking agents (pentaerythritol, cellulose, starch, and dextrin), porophorax (melamine, urea, guanidine, and chloroparaffins), and a polymer binder [1][2][3]. It is known that an important part of the formulation of the fire protection intumescent coating is a binder (resin or film-forming agent).…”

“…The main types of binders used in fire protection intumescent coatings are PVAD (polyvinyl acetate dispersion), liquid glass, acrylic dispersion, acrylic resins, acrylic copolymers, rubber, epoxy, perchlorovinyl, and silicone resins. Numerous standard studies are described in the literature, where the influence of the nature of the binder and its work at a certain ratio of antipyrenes on the final properties of the coating is considered [1][2][3][4][5][6].…”

The influence of basic components of intumescent paint on fire protection properties is studied. The resulting changes in properties are assessed by the intumescence coefficient and thermal analysis data. Influence of the binder polymer composition on fire protection properties under the same conditions was evaluated, quantitatively using the example of fire-retardant water-dispersion paint; the best result was obtained in the formulation based on vinyl acetate copolymers. The brands of ammonium polyphosphate (PFA) from different manufacturers were investigated under the same conditions. The results of the thermal analysis and testing of the physicochemical properties of the samples on various PFAs are presented, with conclusions about their influence on the fire-retardant properties of the paint. The results of the thermal analysis of the influence of orthophosphoric acid, as a modifying additive, on the fire-retardant properties of the paint are presented.
