    Basics of Alkyd Resin Technology - Prospector …

    What is the future of alkyd resins?
    Innovations include the development of bio-based alkyds, which use renewable raw materials, and hybrid systems that combine alkyds with other resins to enhance their properties. The market for alkyd resins is evolving, with increasing demand for high-performance coatings in emerging economies.

    Near-Zero VOC Waterborne Alkyd Dispersions with S…

    Solventborne alkyds continue to remain popular due to their low cost, ease of application, and great versatility. Nevertheless, alkyd coating volume has been forecasted to decline by two percent per year mainly due to the loss of share to coating technologies that can offer higher performance at lower VOC.2 Paints based on waterborne acrylic emulsi...

    When choosing to develop WB alkyd technology, a route to disperse hydrophobic, high-molecular weight/viscosity resins into water without any hydrophilic modification of the alkyd was implemented. It was hypothesized that these dispersions would yield WB alkyd coatings that maintained the excellent gloss, adhesion, and resistance properties associat...

    Early into formulation development of the mechanically dispersed alkyd resins, it was discovered that traditional WB alkyd coating formulation strategies did not give acceptable coating performance with this new class of WB alkyd dispersions. Since additives recommended for WB alkyds were designed to work with more hydrophilic resins, it was necess...

    Once satisfied with a near-zero VOC (<5 g/L) formulation (Table 5),we compared the performance of the SO and MO WB alkyd dispersions, formulated at 14% PVC, with six commercial solventborne alkyd paints (VOC range 330–600 g/L) and four commercial waterborne alkyd paints (VOC range <5–350 g/L). All the paints were applied at a targeted 1 mil DFT on ...

    Clearly both paints formulated with the SO and MO alkyd dispersions performed very well compared to the commercial options available. In addition, the performance of the SO and MO alkyd dispersions were complementary. Both the SO and MO paints from the developmental dispersions had very high gloss (>85 at the 20˚ gloss reading) and excellent adhesi...
