Abstract

Styrene‐acrylic resin paints having a pigment volume concentration of 31 per cent and consisting of a constant level of ethylene glycol, titanium oxide, water, rheological agent, inhibitor and defoamer and variable levels of dispersant (x), anticorrosion pigment (y) and wollastonite (z) were prepared. Such emulsion paints were applied to the flat carbon steel test panels. The dried paint films were subjected to various standard anticorrosion tests. The results obtained showed different types of relationship between the anticorrosive behaviour of the paints and variables x, y and z. The antifouling properties of the paint films were obtained through corrosion tests in a marine‐industrial environment at ambient temperatures.
