“…Its economic importance encourages the plantation of new forests and helps reducing the migration of people from rural areas to cities. Each pine tree can produce 2.5− 3 kg of raw resin per year (Neis et al, 2019a), and the resin may cost US$ 900 per ton in the Brazilian market (ARESB, 2021), being therefore 30-50 times cheaper than synthetic resins, like polyester or polystyrene.…”

A raw pine resin, which is a cheap, renewable and easily obtainable forest resource, was used to impregnate two different fast-growing solid woods (Eucalyptus grandis Hill Maiden and Pinus elliottii Engelm) and in situ polymerized to improve their hygroscopic, chemical, morphological, mechanical, and thermogravimetric properties. Biodegradation resistance against subterranean termites and white-rot fungus was also addressed. The treatment yielded changes in colorimetric properties, dimensional stability and surface hydrophobicity. Compared to its respective untreated wood, the treated pine one presented increases within 40-50 % in ASE, whereas the treated eucalyptus wood showed negative values around -15 % in this same comparison. Increases in MOE (70 %) and MOR (50 %) were obtained for the pine wood, whereas the same properties were unaffected for the eucalyptus wood. Thermal and biological properties of both woods were also positively affected. These results were associated with the solidified raw pine resin inside the wood structure, which was confirmed by infrared spectroscopy and SEM images, especially for the pine due to its large and long tracheids, as well as its lignin content and overall composition.

“…Rosin is obtained through the distillation process of pine resin. The most important uses of rosin are: manufacture of adhesives, printing ink, insulating materials for the electronics industry, synthetic rubber, chewing gum, soaps and detergents due to its mixture between abietic acid and isopimaric acid [ 6 , 9 , 10 , 11 , 12 , 13 ]. Rosin remains as a non-volatile fraction after distillation for turpentine separation.…”

Rosins and turpentines present in pine resins have been widely used both industrially (coatings, electronics and paint) and pharmaceuticals (ointments). Among the main components of these matrices is abietic acid. This study focuses on the characterization and evaluation of the quality of rosins and turpentines in addition to the quantification of abietic acid in rosins. Rosin and spirit of turpentine were obtained separately through the distillation method from P patula and P. oocarpa resin, species grown in the Department of Cauca-Colombia. Resin-tapping was made using the traditional method (cup and gutter). Quality indicators were determined according to ASTM standards. Solubility tests and identification of functional groups were performed on the obtained rosin by ultraviolet-visible spectroscopy (UV-Vis), infrared (IR) and nuclear magnetic resonance ( 1 H-NMR). The abietic acid present in the rosins was determined by high performance liquid chromatography (HPLC). According to their high acid value and low percentage of unsaponifiable matter, the extracted rosins are considered of medium-high quality. Quantification of abietic acid by HPLC showed 14.85 ± 0.24% and 16.09 ± 0.11% for P. patula and P. oocarpa rosin respectively.

“…Its wood has many traditional applications, including the production of cellulose, paper, furniture, and structural parts (Missio et al 2015). Also, its resin has noble uses, such as the production of paints, adhesives, varnishes, and so on (Neis et al 2019).…”

Micro-and nanoparticles of aluminum oxide (alumina) have been used to confer increased flammability to polymers. In the present study, different weight fractions of alumina nanoparticles were impregnated into a traditional softwood and the flammability of these treated woods was studied. Sodium polyacrylate (SPAC) was used as a surfactant and also as a positive control. The influence of the treatment in physical (apparent density), mechanical (static bending and hardness), and thermal (flame retardancy and thermal stability tests) characteristics were evaluated. The presence of alumina nanoparticles in the wood ultrastructure was confirmed by means of SEM/EDS analyses. Compared to the untreated pine wood and that wood impregnated with neat SPAC, the impregnation of alumina contents within 0.3-0.5 wt% reduced the flame spreading of the studied pine woods. Also compared to the untreated wood, similar thermal and mechanical properties were achieved. The studied pine wood became less flammable with alumina impregnation, and there was no detrimental effects to its mechanical properties.
