Organic hydrocarbon solvents are used in solvent-based epoxy resins. The presence of organic volatile solvents in the coating formulation creates a risk to the environment. It is now vital to produce water-based coatings in order to minimise environmental damage. As a result, Shunli Zheng et al. designed a water-based epoxy resin coating that is further enhanced with nano pigments to increase the coatings' functional properties. Bio-based epoxy resin, silane-based coupling agent, and hydrophobic curing agent were used to create hydrophobic coatings. The results reveals that corrosion prevention efficacy of coating was increased to 93.75 percent .
