Biobased Succinic Acid Can Replace between 20-35% of Petro-based Phthalic Anhydride

Succinic acid provides significant opportunity to improve the biobased carbon content of alkyd formulations

October 9, 2014
Ecoat and BioAmber Inc. have initiated a study on the partial replacement of petro-based phthalic anhydride (PA) by BioAmber Inc.’s biobased succinic acid in pentaerythritol alkyd resins (Penta resins).
The preliminary findings suggest biobased SA can replace between 20-35% of the PA, producing a polyester alkyd resin with improved b* color values while maintaining adequate drying time and Persoz hardness values when formulated into mattbased alkyd paints. This study builds further on the commercial introduction of Ecoat’s Secoia® 1404 biobased alkyd binder emulsion.
