Title
New fatty acid based monomers for waterborne polyurethane wood coatings
Abstract
Trends in wood coatings are driven to waterborne systems and to renewable resources. Vegetable oils are well known for wood coatings, e.g. alkyds or polyurethane dispersions. In this context fatty acid methyl ester and derivatives thereof turn out to be an alternative to technical fatty acids and vegetable oils. High contents on hydrophobic oil based monomers improve hydrophobic and oleophobic properties. In this study the synthesis of fatty acid methyl ester derivatives, the preparation of coating resin and the final coating formulation are described. Two types of waterborne coating resins, two-pack system and UV-curing, were applied on beech wood samples to investigate the impact to the resulting coating film properties.
