Finding the right UV-curing waterbased dispersions - a first orientation - Bayhydrol®

This overview of our polyurethane dispersions shows in a simplified way the main characteristics of this raw material line for UV-curing coatings. It is designed to facilitate a first orientation in our large portfolio of coating raw materials. Depending on the desired properties of the end products and your specific formulation requirements other grades might be more suitable. Please contact our experts if you need help with your formulation.
