Acrylic dispersions based on sugar for waterborne wood coatings
The finiteness of fossil feedstock and environmental consciousness forces he substitution of solvent-borne coatings by waterborne products and usage of renewable raw materials. Acrylic dispersions are one of the most important classes of binders in the coating sector. Novel polymer dispersions with high proportion of renewable resources are being investigated at Fraunhofer WKI as binders for waterborne adhesives and coatings for wood and wood-based materials. Sugar derivatives are incorporated in acrylic dispersions, which exhibit equal and also novel properties compared to the commercial petrochemical products. From low-molecular saccharides as starting material radically polymerisable sugar methacrylates were copolymerised with commercial and renewable acrylic monomers by means of emulsion polymerisation. Renewable resources are present at a rate of more than 60 % based on the solid content of the binder. The generated lab-scale product is preferably suitable for furniture lacquers.
