“…supports the structure of the modified castor oil. The peak at 156 ppm is assigned to the carbon of the –NHC=O group, and the peak at 173 ppm is due to the carbonyl of the ester groups of the CO. All the spectral data are in good agreement with each other, and they prove the structure of the MCO .…”

Modification and use of natural products have gained a lot of interest in recent years due to their environmental friendliness and their availability from different sources. In this study, (castor oil)-based photo-curable highly hydrophobic coatings were prepared and characterized. Castor oil was first modified with 3-isocyanatopropyltriethoxysilane and then hydrolyzed prior to the coating preparation. The resulting precursor was mixed with norbornyl acrylate and hexanediol diacrylate, and highly roughened hydrophobic coatings were prepared with the aid of fluorinated/nonfluorinated alkoxysilane coupling agents and hydrophobic fumed nanosilica particles. The coatings were applied on borofloat glass. The addition of fluorine and nanosilica showed a significant impact on the properties of the coatings. As the fluorine and nanosilica contents were increased in the formulations, flame retardancy and the contact angle values of the coatings increased. The surface roughness of the coatings increased with the addition of hydrophobic fumed nanosilica particles. Also, the relation between the surface energy and the contact angle values of the coatings was investigated.

“…CO can also be converted to a number of derivatives, especially to increase the coating ability (2). In general, one of the most important modifications in vegetable oils is epoxidation (3). Figure 1 shows CO and epoxidized castor oil (ECO) structures.…”

New inorganic-organic hybrids were synthesized through the reaction of castor oil (CO) or epoxidized castor oil (ECO) with tetraethoxysilane (TEOS). The mass proportions of ECO/TEOS varied from 90:10 to 60:40, and films of the material were thermally cured. An IR spectroscopy analysis was performed, and macro-and microscopic properties such as adhesion, hardness, swelling in toluene, microstructure (scanning electron microscopy), and T g were investigated as a function of the proportion of their inorganic-organic precursor. Morphologic studies showed that the hybrid films were homogeneous when lower proportions of the inorganic precursors were used. Hardness and tensile strength increased with TEOS concentration, whereas swelling in toluene decreased with TEOS concentration. Good adhesion was observed throughout the hybrid series. Paper no.

“…As fontes primárias destes óleos são o coco, o milho, a semente de algodão, a palma (Opuntia cochenillifera), a azeitona, o amendoim, a semente de linho, o cártamo (Carthamus tinctorius), a soja, a semente de girassol e a semente de colza (Brassica napus) [31]. Segundo vários investigadores [64][65][66][67] [31]. Exemplos de utilização para madeira incluem o óleo de linhaça epoxidado para criar uma resina que pode ser empregue como uma cola ou um material de revestimento superficial [68] e colas naturais à base de óleo de soja como substituto de resina de tipo poliéster em diversas aplicações [69].…”

ResumoNos últimos anos tem-se verificado um interesse crescente pela área das colas naturais, em particular na produção de placas de derivados de madeira para utilização no interior das construções. Estas colas parecem ser uma boa alternativa às colas sintéticas, derivadas do petróleo, pois, ao contribuírem para uma melhor qualidade do ar interior associada a uma menor incorporação de energia no produto final, apresentam vantagens interessantes em termos ambientais e de saúde. Nesse sentido fez-se uma revisão da bibliografia sobre a utilização laboratorial e mesmo semi-industrial de colas naturais em placas de derivados de madeira. São apresentados e discutidos alguns exemplos de materiais que estas colas aglutinam, bem como as suas características finais com vista a futuros desenvolvimentos experimentais de placas fabricadas a partir de resíduos agrícolas comuns. © 2015 Sociedade Portuguesa de Materiais (SPM).

This type of adhesives could be a good alternative for petroleum based synthetic adhesives as bio-based adhesives can contribute for healthier indoor environments and, simultaneously, present lower embodied energy. For the previous reasons a bibliographic review was conducted, on the use of bio-based adhesives for the production of wood-based building panels. Some examples of the adhesives, the type of applications and the characterization of the resulting products are presented and compared, bearing in mind contributing for a future increase of research in this area.
