Abstract

The investigations of the waterborne anticorrosive composition containing non-toxic pigments and binders with different chemical nature have been carried out. The effect of binders, pigments, extenders and the level of pigmentation on the structure of coatings (Hg porosity test, DMTA) and on the protective properties (corrosion chambers, EIS, SVET) were tested. The test results show that protective properties of the coatings depend on the chemical composition of binders and the mechanism of film formation. The impact of pigments on protective characteristics of the coatings is connected with their chemical composition, physical shape and the level of pigmentation. The application of the statistical analysis of the results allows to define the weight of particular components of paints in shaping protective properties of the coatings and the selection of the optimum composition.
