Tailored Biobased Resins from Acrylated Vegetable Oils for Application in Wood Coatings

The modern coating market is dominated by acrylic, polyurethane, and polyester polymer resins produced from unsustainable fossil resources. Herein, we propose the preparation of biobased components to produce functional solvent-free wood coatings with enhanced performance properties. Acrylated rapeseed, linseed, grapeseed oils were prepared via a one-step synthesis used as basis for control resin viscosity fatty acid content. A combination vegetable oil acrylates was matrix monomer propoxylated glycerol triacrylate (GPT) selected tailor properties UV crosslinked network. During polymerization, GPT induced two-phase microstructure indicated an SEM analysis. possibility generating tailored in final material examined this study. addition increased storage modulus up five-fold, crosslink density two-fold at 20 °C, glass transition temperature 10.2 °C. Pull-off adhesion tests showed strength 1.21 MPa. In addition, photo-oxidation effect on samples, i.e., aging, assessed microhardness, sliding friction, optical microscopy. Coatings microhardness value 250 MPa, while coefficient friction (μ) range 0.21 0.88.
