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.
Pigments are important in paints as protectors from corrosion and inhibitors. The main inhibitor pigment made and used in Spain is zinc phosphate.Zinc phosphate pigment was applied to epoxydic resin-painted carbon steel test bars, subjected to standardized tests, in order to ascertain the corrosion protection.The results show that ohmic resistance values decrease over a period of time. Also, the greater the amount of zinc phosphate, the greater the ohmic resistance and resistance to corrosion. The characterization consisted of EIS tests.In the Spanish paints industry, the most commonly used anticorrosive pigments are those conferring an inhibitor effect. Despite being toxic, large amounts of chrome phosphate are also produced, properly labelled, sold and used in Spain, to a larger extent, for undulated steel sheet coil coating in plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
