The effect of a surface coating with an aqueous solution containing synthetic diammonium hydrogen phosphate fire retardant and vacuum pressure impregnation retardant, potassium acetate, natural polymeric arabinogalactan, to improve the resistance selected properties structural fir (Abies alba L.) wood was investigated in this article. combustion characteristics were investigated, heat reflects presence retardants. Changes content cellulose, hemicelluloses, holocellulose, lignin, extractives characterize chemical changes caused by these factors. relationship between chemically modified as consequence flame retardants assessed using Fourier transform infrared spectroscopy. results showed that effectiveness against ignition burning when applied always higher than case coating, even solutions low concentrations. In phosphate, 5% concentration sufficient provide suitable retardancy. Further, degradation depolymerization cellulose occurred only at temperatures 460 470 °C. Low concentrations limit loss environment consequent ecological impact.
