“…A combination of charring and foaming of the heated polymer surface causes the intumescence process. The reaction mechanism is described in detail elsewhere, e.g., in [15], [16]. The following stages may briefly describe the reaction mechanism for intumescent coatings.…”

Intumescent paints’ behaviour is investigated for protecting wood pre-treated with phosphate or a silicate-based flame retardant. Additionally, the ageing effects of intumescent paint under several conditions are investigated. The cone calorimeter is applied, measuring the reaction to heat responses and the char development. Pre-treatment showed an improved fire performance of samples with intumescent coatings. The effects depend on the moisture contents and the homogeneity of the pre-treatments. Also, the experiments showed differences in fire resistance depending on the ageing method. UV exposure ageing retained the heat-insulating properties, while samples immersed in acid suffered a drastic reduction of their fire resistance. The latter ageing test increased the char’s pore size resulting in a reduced expansion factor and reduced thermal insulation performance of the intumescent coating.

“…The effect of expanding bubbles on the temperature field, particularly, cannot be deteriorated. Additionally, a refined selection of components—char formers, carbonizing, dehydrating substances, and modifiers—is vital to make the intumescent flame retardant effective, allowing for a maximum degree of carbonization and, thus, an efficiency of the protective char [ 137 ].…”

“…This branched or unbranched polymeric compound’s chain length ( n ) varies, where n can be greater than 1000. Short linear-chain APPs (crystalline form I (APP I)) ( n = 100) are more water sensitive (hydrolysis) and less thermally stable compared with longer branch-chain APPs (crystalline form II (APP II)) ( n > 1000), which have very low water solubility (0.1 g/100 mL) [ 137 , 145 ]. APPs are known to be nonvolatile and stable compounds.…”

This review provides an intensive overview of flame retardant coating systems. The occurrence of flame due to thermal degradation of the polymer substrate as a result of overheating is one of the major concerns. Hence, coating is the best solution to this problem as it prevents the substrate from igniting the flame. In this review, the descriptions of several classifications of coating and their relation to thermal degradation and flammability were discussed. The details of flame retardants and flame retardant coatings in terms of principles, types, mechanisms, and properties were explained as well. This overview imparted the importance of intumescent flame retardant coatings in preventing the spread of flame via the formation of a multicellular charred layer. Thus, the intended intumescence can reduce the risk of flame from inherently flammable materials used to maintain a high standard of living.

“…Many components can be used to create intumescents [8][9][10], but most commonly compositions include melamine, pentaerythritol, ammonium polyphosphate and titanium dioxide; interactions between them lead to forming the stable and isotropic charred layer. For the long time [11] titanium dioxide has been considered only as a white pigment, but our previous research [12] shows that titanium dioxide also takes part in formation of a charred layer: it acts as a catalyst of pentaerythritol's decomposition and as a nucleating agent in forming of organic-phosphorous foam [12,13].…”

The paper overviews the process of thermolysis of fire-retardants based on melamine, ammonium polyphosphate and pentaerythtritol and containing titanium dioxide of different trademarks. The role of titanium dioxide as a component of fire-retardants is revised. Titanium dioxide was perceived only as white pigment, but this paper states that the properties of a charred layer forming from an intumescent coating depend on the properties of titanium dioxide's species, such as surface treatment and crystalline structure. This statement is proven by using thermal analysis of intumescents with different titanium dioxide's trademarks; it shows that rutile titanium dioxide helps forming a charred layer with the highest thermal stability thus fire retardant efficiency grows up. It means that the knowledge of processes which occur in intumescents based on primary products with different qualities helps to create fire-protective compositions which will perform more reliable in case of fire.
