The paper is the second part of the article that presents experimental results of the research developed in order to obtain innovative systems for corrosion protection of steel. There were created three recipes of an innovative type of a coating, starting from an acrylic compound in aqueous dispersion, with ceramic microspheres, in which it was introduced, in different proportions, a kaolin additive. Each product was applied on steel surfaces, in four - layered systems. There are presented results referring to the systems behavior during their exposure to corrosive environments in accelerated laboratory conditions that simulated three types of aggressive climate conditions. The adherence of the systems to the steel surface indicated a new possible merge between nanotechnology and the use of natural resources, and also a new possible direction for the use of kaolin in the coatings industry, in order to obtain a new type of coatings with a good reaction to the aggressive actions of the current climate from various countries. There are also analyzed, by comparison, the results obtained on the three and four-layered systems, respectively (the dates for the three-layered systems being initially presented in the first part of the paper).
