The Use And Modification Of Different Vegetable Oils For Anticorrosive Paint

Long oil modified alkyd resins have a wide usage as film forming substances with protection characteristics at anticorrosive paints. Alkyd resins have replaced the basic components of the anticorrosive paints, which formerly were produced through thermo-chemical processing of colophon products with polymerized vegetable oils. Anticorrosive paint was prepared from long oil alkyd resin. The process is known as Alcoholysis method combined with azeotropic esterification with refluxing xylene which carries away the reaction water. The physical properties of anticorrosive paint produced using different kind of oils like vegetable oil (soybean), coconut oil and olive oil has been compared with the standard of anticorrosive paint that was investigated using long oil alkyd resin and colophon product i.e. in terms of viscosity, acid value, drying time (surface drying time and full paint drying time) and thickness of the paint. Physical and chemical properties of olive oil and vegetable oil were compared using maleic anhydride and phthalic anhydride. The use of maleic anhydride up to 2 % instead of phthalic anhydride gives better result according to standard.
