Abstract

Silicone–epoxy coatings containing siloxane-modified polyacrylate (SMP) were prepared. The effects of SMP on the hydrophobicity and water uptake behavior and on the corrosion resistance provided by the coatings were examined using contact angle measurements, glass-transition temperatures, and electrochemical impedance spectroscopy. The water uptake behavior of silicone–epoxy coatings with higher SMP content decreased to a greater extent for coatings with higher hydrophobicity. The anticorrosion protection of 2024 Al-alloy by silicone–epoxy coatings containing SMP correlated well with their water uptake and hydrophobicity.
