Most promising types include the diesters of itaconic acid and esters of (meth)acrylate monomers prepared with plant-based alcohols. Other plant-based monomers show issues with either too slow, or too high reactivity, or with lacking commercial availability. Applying the preferred and commercial available monomers in emulsion polymerisation can yield water-based and partially plant-based binders showing film properties in industrial coatings that are similar to those found for paints based on commercially available fossil-fuel based binders. At this point in time, polymeric binders with plant-based contents of around 40% can be achieved (calculated on total carbon content). New developments with even higher plant-based contents are, however, foreseen to be available within five years from now. Note de contenu : - Table 1.

It is capable of being incorporated into low volatile organic compound (VOC) formulations and combines good appearance, film formation and toughness with excellent hardness and abrasion resistance. In this study, we have evaluated the self-crosslinking PUD in various applications ; from high performance wood coatings to protective coatings for rigid plastics and as a top coat for metal. In this paper, we demonstrate the application properties of this resin, such as its hardness development, resistance to chemicals, adhesion, weathering etc. We also validate the versatility of this resin in several applications and assess the film formation and mechanical properties of the PUD. Lastly, we discuss how these influence the performance of the coatings.

In response, many manufacturers are operating their wet grinding systems with increasingly smaller grinding beads and maximum power input within the limits of their capacities. To help them be able to produce sustainably and safely at this level, the author reports from Bühler, on how it is launching digital services over the next few years, which can be used to optimise the production process beyond machinery and site limitations.

New developments now create a novel design, which offers environmentally sustainable improvement to anti-fouling performance in marine environments. This paper addresses how the use of select, tailor¬made structure modified fumed silice technology (SMS) formulated synergistically with copper oxide (Cu20) improves the antifouling behaviour and life-cycle performance of antifouling coatings. Supporting mechanical stability results will show how technology helps reinforce film properties. A brief review of the model to explain the positive effects of structure modified fumed silice in Cu20 based antifouling coatings will be presented. Specific performance enhancements of increased film stability and a reduced leaching of copper ions will be addressed.
