Abstract

Crude glycerol (CG), a low-value byproduct from the biodiesel industry, has a significantly different composition compared to pure glycerol. Generally, crude glycerol contains various impurities, such as methanol, water, soap, free fatty acids (FFAs), fatty acid methyl esters (FAMEs), and glycerides. In this study, crude glycerol-based waterborne polyurethane (WPU) coatings were prepared from polyols synthesized using crude glycerol as a sole feedstock via a thermochemical conversion process. The corrosion properties of coatings were characterized by electrochemical impedance spectroscopy (EIS), polarization measurement and salt spray test. The initial experimental results show that crude glycerol-based WPU coatings have a considerably enhanced corrosion resistant performance of metallic substrate.
