Finding the right dispersion - a first orientation - Bayhydrol®


This overview of our polyacrylate, polyester and polyurethane dispersions (Bayhydrol®) shows in a simplified way the characteristics of our major raw materials for waterbased coating systems. It is designed to facilitate a first orientation in our large portfolio of coating raw materials. The starting point is a product with a well-balanced overall property profile in the middle. 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.
