Dispersing agents that are suitable for all types of pigments create opportunities to simplify the process of producing high-performance waterborne pigment preparations without the need for extensive pre-testing phases.
Arkema announced that its SYNAQUA® 4856 alkyd has been approved to carry the United States Department of Agriculture (USDA) Certified Biobased Product label.
Even though the coating properties of the new alkyd formulation matched perfectly the properties of the old formulation, what had been the unforeseen consequence of changing one oil for another in the formulation?

In recent years, the focus has been on the development of durable and sustainable coatings, looking for solutions that would support the transition from fossil to bio-based products with equivalent performance.
This study has confirmed benefits from use of liquid polybutadiene polymers in solvent-based coatings with additional enhancements seen from a new liquid polybutadiene.
Lactide-based alkyd resins can help coatings formulators to meet new targets for lower VOC content and produce coatings with a reduced carbon footprint.
Extensive testing demonstrates that this dispersion technology enables waterborne alkyds that offer a performance level significantly exceeding currently available waterborne alternatives and equal to – and in some cases better than – solventborne alkyds.
A variety of technologies are under development, including waterborne polyolefin and alkyd dispersions, acrylic coatings for metal, isocyanate-free polyurethane coatings and BPA-free can coatings.
