Troubleshooting Waterborne Polyurethane Dispersion Formulations: Common Defects, Causes, and Solutions
Waterborne PUD troubleshooting starts with understanding how polyurethane dispersion properties, formulation components, and application conditions affect coating performance. However, during formulation and application, coating manufacturers may encounter problems such as foam, pinholes, poor adhesion, cratering, uneven leveling, and storage instability. These defects do not always originate from the polyurethane dispersion itself. They may also result […]
