“…Commonly, polymeric resins are categorized into epoxy and ester ones, in which ester resins are utilized for low-performance applications while epoxy resins for high performance [ 30 , 36 , 138 , 139 ]. Epoxy resins have more adhesion tendency to the surface of glass and carbon fibers than ester resins.…”

“…Several studies have been reported to modify the lignin and enhance compatibility with polymers and mechanical properties for high-performance applications to overcome these drawbacks. Up to now, a large amount of research has been performed on bio-based thermoplastics such as bismaleimide/eugenol [ 17 ], poly(lactic acid) [ 18 ], bio-poly(ethylene terephthalate) [ 19 ], poly(butylene succinate) [ 20 ], polyhydroxyalkanoates [ 21 , 22 ], poly(ethylene 2,5-furandicarboxylate) [ 23 ], and also on thermosets such as itaconic acid [ 24 ], isosorbide [ 25 ], composite of cardanol novolac/bismaleimide [ 26 ], plant oil [ 27 , 28 ], eugenol [ 29 ], and polyesters [ 30 ]. On the other hand, average research progress has been published on preparing thermoplastic and thermosets resins with lignin.…”

By increasing the environmental concerns and depletion of petroleum resources, bio-based resins have gained interest. Recently, lignin, vanillin (4-hydroxy-3-methoxybenzaldehyde), and divanillin (6,6′-dihydroxy-5,5′-dimethoxybiphenyl-3,3′-dicarbaldehyde)-based resins have attracted attention due to the low cost, environmental benefits, good thermal stability, excellent mechanical properties, and suitability for high-performance natural fiber composite applications. This review highlights the recent use of lignin, vanillin, and divanillin-based resins with natural fiber composites and their synthesized processes. Finally, discussions are made on the curing kinetics, mechanical properties, flame retardancy, and bio-based resins’ adhesion property.

“…The full procedures of the retrieval of the different fatty acids can be found in literature. 43 EMO was retrieved by methanolysis at 60 C from epoxidized linseed oil. The obtained methyl esters were rst extracted in nheptane/deionized water (1 : 1) 4 times and then puried by column chromatography in n-heptane/EtOAc gradient solution.…”

Selective enzyme catalysis is a valuable tool for the processing of monomers into value-added materials. In the present study natural resources were used to retrieve an u-hydroxy fatty acid monomer containing an epoxide functionality. A procedure was developed for the synthesis of dual-functional oligomers by utilizing lipase catalysis in a one-pot synthesis route. The chemoselectivity of the enzyme allowed addition of thiol monomers to the retrieved epoxy monomers, without harming the epoxides, achieving a thiol-epoxy functional polyester resin. The synthesis reached full conversion (>99%) after 8 h. It was possible to selectively crosslink the resin through UV-initiated cationic polymerization of the epoxides into thiolfunctional thermosets. The curing performance was followed in situ by real-time FTIR. The thiol groups on the surface of the film were accessible for post-modification. † Electronic supplementary information (ESI) available: ESI One-pot enzyme-catalyzed synthesis of dual-functional polyester macromers towards surface active hydrophobic lms.

“…Therefore, the development includes a considerable amount of laboratory work, from synthesis and mixing of ingredients to the testing of the effectiveness and durability of coatings [12]. With coatings having to ensure adequate protection for as long as possible, laboratory testing often takes place under strict conditions that require well-trained professionals and expensive laboratory equipment.…”

Digital Transformation Reduces Costs of the Paints and Coatings Development Process

et al. 2020

An essential characteristic of the new product development process is to develop a new marketable product in the shortest possible time with the lowest reasonable costs. Therefore, the key factor of the process is efficiency. The paints and coatings industry development process contain numerous laboratory tests to determine the appropriateness of new formulation. It is proven that digital transformation can reduce the number of laboratory tests and consequently shorten the throughput time of the development process. This raised the question of whether the faster development process also reduces the process’ cost, or they even increase due to information and communication technology implementation. Therefore, the research’s purpose was to determine whether reducing the number of laboratory tests, based on the implementation of information and communication technology (ICT), affects reducing costs in the paints and coatings development process. The conventional process and the redesigned process of paints and coatings development were used as the basis of the research. The comparative analysis of the costs incurred during the development process was made. The analysis compares the types and amount of incurred costs. The article proves that digital transformation has a significant impact on up to 48% on reducing costs of the paints and coatings development process.
