Metal Adhesion and Corrosion Resistance of Coatings

By Greg Monaghan, Nerissa Swaim, Benjamin Estill, and Victoria Winston

Corrosion has been defined as an interaction of a material with its environment that results in an irreversible degradation of the material.1 Although organic coatings are often used to prevent the surface of a material from coming into contact with the corrosive environment, compromises in the formulation of many water-based coatings to improve adhesion can reduce their effectiveness at abating corrosion. Recent work with hybrid styrene acrylic polymers containing hydrophobic resin has shown that an improved balance of properties is possible compared to conventional acrylic or styrene acrylic polymers.
