Nowadays, the corrosion effect is one of the key factors from an economic, safety and ecological point of view. Modern solutions are environmentally friendly waterborne coatings for corrosion protection. The use and development of waterborne coatings have grown considerably due to regulations which limit the emission of volatile organic compounds in the air. With the aim of contributing to our present knowledge, this PhD thesis examines the properties and behavior of waterborne coatings at different drying temperatures and thick film application, and it especially examines the protection efficiency of waterborne coatings systems. Tests have been simultaneously carried out on solvent borne coatings. In this research, electrochemical polarization methods, electrochemical impedance spectroscopy and accelerated corrosion tests in chambers have been used. The protection properties of the coating system have been examined by alternate immersion. The drying of the coatings was examined by periodical monitoring of hardness, determining the physical properties of coatings, and measuring the drying time. The properties of the layer at different drying temperatures and thick film application were observed using a scanning electronic microscope. The research findings represent a contribution to our understanding of protection properties and hardening mechanisms of waterborne coatings under different drying conditions.
