Anti-corrosion waterborne polyurethane coatings

Abstract

Corrosion is a common phenomenon between materials and substances in their environment. Corrosion limits the use of metals for various purposes and increases costs in industries. Many advanced methods have been reported to prevent the corrosion of metal tools. This chapter discusses many topics related to corrosion mechanisms, inhibition routes, corrosion analysis, and mechanisms of waterborne polyurethane and its composites for corrosion protection. Waterborne polyurethane is an eco-friendly polymer that is ideal for a wide range of applications due to its properties, such as flexibility at low temperatures, moisture resistance, resistance to pH changes, quick drying, and easy cleaning. To create an effective coating, it is necessary to prepare highly stable dispersions with practical inhibitory effects, proper packing, high cross-linking density, suitable additive content, and strong adhesion to the substrate. In this chapter, the current literature and research on using waterborne polyurethane and its composites as an anti-corrosion coating are studied in detail to provide a comprehensive overview of how anticorrosion coatings work and what can improve their anti-corrosion properties. © 2023 Nova Science Publishers, Inc.
