Coatings are an essential part of everyday life. Their applications range from low-tech surfaces such as walls, furniture, and consumer appliances, to high-performance technologies such as cars, airplanes, and military equipment. Over the past 30 years, the market share of waterborne coatings has been increasing at the expense of solvent-borne formulations. These water-based systems are more environmentally friendly and healthier for consumers. However, waterborne coatings cannot yet compete with solvent-based coatings in terms of durability and performance.
