Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, a facile and cost-effective approach has been developed for fabricating antibacterial and antistatic waterborne polyurethane (WPU)-based coatings by using Polyaniline-Copper@Zinc oxide (P-Cu@ZnO) ternary nanohybrid as a multifunctional additive. The solid-state reaction of copper acetate and zinc acetate salts led to the synthesis of copper clusters on the ZnO nanoparticles (Cu@ZnO). The obtained Cu@ZnO nanoparticles were intercalated with polyaniline (PANI) chains to prepare the P-Cu@ZnO nanohybrid. FTIR, XRD, UV–Vis, and FESEM analyses were used to characterize the structural, crystallographic, and morphological properties of the synthesized nanohybrid. Adding P-Cu@ZnO nanohybrid to the WPU matrix not only improved adhesion strength of the coatings but also enhanced their scratch resistance compared to the pristine WPU coating. Moreover, incorporation of the obtained nanohybrid into the WPU coatings caused electrical surface resistance of the obtained coatings to reach 1.2 × 10+8 Ω/sq, so, these coatings gained the optimum electrical surface resistance to be counted as an antistatic coating. Also, the results of the colony counting test showed that the modified coatings could reduce the Staphylococcus aureus and Escherichia coli bacteria growth by about 86% and 74%, respectively.

Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Comparisons between matte emulsions containing flash calcined kaolin and opaque polymer, providing advantages for each formulation.
Flash calcined kaolin and opaque polymer are both technologies that can each influence the micro void structure of high PVC matt emulsions, however, considerably less Opacilite is required to match the opacity and scrub resistance. Typically, it is possible to replace the opaque polymer in high PVC matt emusion just by 60 to 65% of its weight of Opacilite and the balance with water. admittedly, since opaque polymer is a non-film forming emulsion polymer it does provide better overall paint colour and a lower porosity. In the two examples discussed in this work, the DE values were just greater than 0.5, however, it could be argued that this difference is acceptable in some applications. A significant advantage of Opacilite's irregular particle shape and intrinsically sealed micro voids is that Opacilite provides lower sheen and improved wet opacity. The greater differential between the CPVC and the PVC in the Opacilite reformulation reduces the internal stresses during drying and provides better mudcrack resistance. Finally, the overall formulation cost using Opacilite is lower, with estimate savings of at least €0.02/litre, irrespective of the matte emulsions titanium dioxide content.En ligne : https://drive.google.com/file/d/1volu_fxkbTwNmIiUboAB-GiTOjZ-7NSw/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27201

The combination between conventional polyurethane dispersions and acrylic emulsions offer an excellent cost/performance balance. There are two approaches possible, or the physical blend between separately formed polymer system or the chemical blend between the both systems where one system is reacted in the presence of the other one.
In most cases is the cost/performance balance better for hybrid systems than for physical blends.Note de contenu : - Solvent based coatings

Primaire (revêtement)Index. décimale : 667.9 Revêtements et enduits Résumé : The amount of volatile organic compounds (VOC) used in coatings continues to be reduced, due to environmental legislation and much R&D is dedicat¬ed to reducing VOCs in coatings while maintaining the same performance and appearance attributes. Waterborne emulsions provide feasible solutions to the challenge of meeting VOC regulations.
