Green Anticorrosion Coating With Low Vocs Emission Using Moringa Oleifera Leaves Extract

Air pollution is an increasing prevalence of environmental diseases. previously, hazardous air pollutants (haps) on the ozone layer, which primarily constitute volatile organic compounds (vocs), have become a major public concern. as a result, the environmental protection agency (epa) has introduced a strict regulation on the limit of vocs content for various daily products such as paints and solvents to reduce the risk. hence, the study aims to develop an eco-friendly coating with low vocs content per the imposed regulation by deploying the leaves extract of moringa oleifera (moe) for marine vessel protection. the formulated coating was characterized by using optical, electrochemical, and morphological analysis to study the effectiveness of its barrier property against the aggressive solution of seawater. additionally, measurement of its vocs content was conducted following the astm d2369-03. the results obtained suggested that the incorporation of 1 wt.% of moe of c2 increased the resistivity of coating in reducing the penetration of ionic electrolytes up to 91.2% while exhibiting the traits of low vocs content category at a value of 198 g/l.
