Coating is widely used as corrosion prevention and also for aesthetic property. The composition of common industry coating consists of binder, pigment extender, solvent and additive. This coating composition is detrimental to the environment because it contains Volatile Organic Compound (VOC). Besides that, the synthetic polymers are neither renewable nor biodegradable which impact the sustainability of the nature. With an intention to provide alternative solution for global coating issues and highlight the application of green technology, the effectiveness of tapioca polysaccharides(TPS) based coating for corrosion prevention of carbon steel is evaluated. The basic performance can be determined by conducting standard coating testing with salt spray testing as per ASTM B117 and adhesion testing as per ASTM D3359. With 85% epoxy- 15% TPS biopolymer mixture, the coating showed satisfactory anti corrosive behaviour in protecting the carbon steel. The adhesion strength of the mixture was also passed the average pressure acceptance criteria used in industry. With the promising preliminary results, the potential of the epoxy-TPS biopolymer coating to contribute to green technology is positive. However, more tests should be conducted to characterize the formulation
