“…These peaks correspond to the asymmetric and the symmetric stretching vibration for CH (CH 2 and CH 3 ) . The highest absorbance in the spectra was produced between 1750 and 1735 cm −1 , which was characteristic of the CO stretching . These peaks were more pronounced in the tall oil‐treated paper‐sheets than in the hydrowax‐treated one.…”

This study was conducted to assess the effect of the pulping by‐products crude tall oil (CTO), distilled tall oil (DTO), and tall oil fatty acid (TOFA) on dynamic water vapor sorption behavior, interfiber strength, and thermal stability of cellulosic paper‐sheets. The results were compared against those obtained in cellulose papers treated with the conventional petroleum‐derived hydrophobic agent hydrowax and in untreated ones. The tall oil treatments caused strong reduction in equilibrium moisture content of the paper‐sheets during adsorption and desorption runs. The same trend was noticed for the hydrowax‐treated papers, however, it was less pronounced than the CTO‐treated and DTO‐treated samples in the relative humidity range of 75–95%. The sorption hysteresis was considerably decreased after the treatments. The ultimate dry‐tensile strengths of the paper‐sheets were significantly reduced by TOFA and hydrowax treatments, while CTO and DTO showed comparable strength as that of untreated control. The ultimate wet‐strengths of the paper‐sheets were improved after the treatments. The thermal stability of the specimens was improved by the tall oil treatments, and the hydrowax‐treated samples illustrated lower degradation temperature than the untreated control. The results are promising for the use of tall oils as alternative hydrophobic agents of cellulosic fiber‐based products, such as wood panels and paper packaging. © 2018 Wiley Periodicals, Inc. J.

“…Toluene (up to 50 %) was added to the premixed polyol with intumescent additives. For the thermal and mechanical test, polyurethane coatings were prepared in the form of free films [24]. For the flammability test, polyurethane coatings, 250 µm -300 µm in thickness, were applied on (100×100×16) mm standard wood (pine) samples.…”

The efficiency of using intumescent flame retardants in polyurethane coatings based on tall oil fatty acids esters was assessed. The influence of the content of each of the flame retardants (ammonium polyphosphate, melamine and pentaerythriol) separately on the flammability parameters of wood samples with polyurethane coatings in a cone calorimeter test, as well as on the thermal and mechanical properties of the polyurethane itself, was investigated. The effect of the ratios of double and triple combinations of the mentioned flame retardants on the specified properties was studied. It has been found that, for the given type of polyester urethane, ammonium polyphosphate decreases the flammability of polyurethane most. Melamine, and melamine in combination with ammonium polyphosphate decrease the smoke release upon polyurethane combustion.

“…The effects of the melamine phosphate content and the weight proportions in its combination with other FRs on the main parameters of the thermal stability and flammability of polyurethane coating were studied. The mentioned parameters of the new coatings were compared to the parameters of similar polyurethane [12], were used as a polyol.…”

Abstract. The effect of melamine phosphate (MP) on the thermal stability of bio-based polyurethane and the flammability parameters of wood samples with polyurethane coatings was studied. Thermogravimetric analysis and cone calorimeter test at a heat flux of 35 kW/m 2 were used for this purpose. The main characteristics of the thermal stability and flammability of the coating with addition of MP were compared with the characteristics of analogous coatings with addition of ammonium polyphosphate (APP), as well as APP in combination with melamine. It was found that the use of MP as an intumescent additive allows a considerable decrease of most of the flammability parameters of the polyurethane based on tall oil fatty acids, like APP. To reach the maximum effect, it is enough to load in the polyurethane 20% of MP. In contrast to APP, MP reduces also the smoke release of the samples. Using MP in combination with APP at definite weight ratios, it is possible to essentially reduce the flammability parameters of polyurethane coatings, such as PHRR, THR and MARHE.
