Epoxy resins are widely commercialized in the market because of their important applications such as adhesives, protective and decorative coatings. However, their usages have brought in negative impacts on the environment since approximately 70% of the epoxy resins are prepared from toxic petroleum-based precursor bisphenol. Therefore, great effort has been input on the use of bio-based compounds to create an environmentally-friendly epoxy resin industry. In this research, epoxy coatings were prepared from cardanol-based resins and bio-based curing agents furfurylamine (FA) and 1,8-Diamino-p-menthane (DAPM) without the use of any solvent. Hydrophobization was realized by the addition of a fluorine-free additive. The thermal-mechanical and wettability properties of the coatings exhibited a strong dependency on the type of epoxy resin and curing agent. The coatings were also assessed for their anti-icing and anticorrosion performances. The fully bio-based NC514-DAPM coating showed a very low ice adhesion st...
