“…One approach to enhance the functionality and thus the end user value of coatings is the addition of nanoparticles Hischier et al 2015;Nikolic et al 2015;Pilotek and Tabellion 2005;Weiss 1997). Due to their morphology, they have a very large surface-to-volume ratio, which allows them to interact intensively with their surroundings and therefore enhance the mechanical properties of a polymer matrix.…”

Nanocellulosic fillers for waterborne wood coatings: reinforcement effect on free-standing coating films

Coatings fulfill an important function in providing functionality and service life to wood surfaces. In the present study, the potential of nanocellulosic fillers toward improving waterborne wood coating mechanics is evaluated using free-standing coating films. At 2% filler content, significant improvements in static and dynamic mechanical properties were observed. The extent of these improvements was different depending on whether high-aspect-ratio cellulose nanofibrils of short cellulose nanocrystals were used. Chemical surface modification of cellulose nanofibrils did not provide further improvement. The water-vapor sorption properties of the coating films, which were also evaluated, did not show significant effects due to addition of nanocellulose, while optical transparency slightly decreased.

“…A spike in electrical current results in a large indentation and a potential burn through effect on thin metal plates [18]. Also, particularly on the high condition where the spatter is excessive, the appearance of the weld is important [19]. Furthermore, as a result of significant resistance heat, the overheating microstructure is generated in the heat affected zone and then the mechanical properties of the spot weld decreases [16].…”

“…Powder coatings have several clear advantages compared to solvent-based coating systems: low emission of volatile organic components, facile, safe application of the coating, very little waste due to reuse of powder overspray, and the curing process produces a hard, tough and durable coating. [1][2][3][4][5] The dry paint which constitutes a powder coating, consists of a binder resin, a curing agent, pigments, and additives to enhance properties such as flow and to reduce film imperfections. 6,7 The different components are dispersed into the resin using an extruder.…”

In this article, the synthesis of bio-based polyamides for powder coating applications and their evaluation in a solventborne coating system are reported. The M n values of the resins were between 3000 and 4000 g mol À1 and the resins displayed T g values from 60 to 80°C. Both amine and carboxylic acid functionalities (total $0.6 mmol g À1 ) were introduced for curing purposes. The resins were cured with triglycidyl isocyanurate (TGIC) or N,N,N¢,N¢-tetrakis(2-hydroxyethyl)adipamide (Primid XL-552). The curing reaction was followed using rheology which indicated that TGIC achieved higher reaction rates and higher gel contents. The DSC analysis of the cured disks showed that all cured samples were amorphous as is desired for the targeted coating application. The resins required a curing temperature higher than 150°C. Aluminum panels were coated using a solventborne approach and the coatings were cured at 180°C during 1 h. Dewetting was observed on all panels. Network formation was adequate for an amine-functional resin cured with TGIC as indicated by solvent resistance testing. In conclusion, the developed biobased polyamide resins are promising materials to be used as binder resins in powder coating applications.
