It was shown that the flammability reduction effect, when determining the oxygen index and fire resistance rating, is achieved through the formation of a protective foam coke layer. This effect was used to produce intumescent fire-retardant coatings. Optimal ratios of phosphorus- and nitrogen-containing flame-retardant precursors were found. This eliminated the use of pentaerythritol as a carbon source, which inhibits the cold curing of epoxy resins. A polymer matrix is used as a carbon source, which reduces the formation of degradation products during a fire.</p>","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"17 5","pages":"1331 - 1337"},"PeriodicalIF":0.4,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
