Abstract

One of the major directions in the research of protective coatings is the development of environmentally-friendly waterborne coatings that contain a small amount of volatile organic compounds (VOCs) and protect metals from corrosion in different environments. In this paper, curing and corrosion protection properties of waterborne and solventborne epoxy coatings at three drying temperatures 5, 23 and 35 °C were studied. Curing of coatings was studied by measuring the König pendulum hardness during 21 day of drying at different temperatures as well as by testing the physical properties of coatings (Buchholz hardness, elasticity, impact resistance, adhesion, gloss) dried at room temperature. Corrosion protection properties of coatings were studied by conducting the Electrochemical Impedance Spectroscopy (EIS) in 3.5 NaCl solution and salt chamber testing. The analysis of the test results has shown satisfactory corrosion protection properties of waterborne epoxy coatings dried at temperature of 35 °C, while at lower drying temperatures certain limitations in their application have been established. The solventborne epoxy coating show stable protective properties at all tested drying temperatures. © 2014 The Authors.
