Performance of commercial and natural antifouling embedded in rosin modified coated on wood surface

Abstract

Rosin based paint is one of natural source of paint matrix essential in combination of natural biocides for greener and efficient antifouling paint. Performance of new natural lemon biocides and commercial biocides embedded in rosin modified antifouling paint were evaluate by referring to ASTM 3623 – 78a for 30 days. Natural lemon biocides with concentration of 2%, 4% and 6% observed that increase in biocides concentration reduce the percentage of marine growth. Natural lemon biocides with 6% concentration observed similar performance as in commercial antifouling on wood surface due to good interaction. This concluded that natural lemon biocides have a great potential as new natural biocides on wood vessel hull surface.
