Eco-paints from bio-based fatty acid derivative latexes

A series of fatty acid derivative latexes has been incorporated as binders in waterborne paints: methacrylated oleic acid (MOA) and methacrylated linoleic acid (MLA) homopolymers and copolymers of the petroleum derivative monomer methyl methacrylate and its structurally analogous renewable resource monomer alpha-methylene-gamma-butyrolactone. The performance of the resulting paints has been evaluated in terms of hardness, gloss, rheological behaviour and open time and the final properties have been compared with a commercial waterborne paint. Most of the prepared paints showed good performance properties, making these compounds good candidates for their use in the production of sustainable waterborne paints. (C) 2015 Elsevier B.V.
