| Abstract: | Polyesteramide resins (PEA) combine the properties of both polyester and polyamide resins. These resins may be modified with various polyhydric alcohols to produce resins with modified properties. Hydroxy ethyl fatty acid amide (HEFA) is the main source of polyhydric alcohol used in polyesteramide resins. New modified polyesteramide resins were prepared and evaluated as anticorrosive varnish for industrial applications by partial replacement of hydroxy ethyl fatty acid amide (HEFA) with polyethylene glycol (PEG400) without affecting the resin constants. Primer formulations based on these modified resins improve the films properties and show good physicochemical and corrosion inhibiting properties. |
