What is The Preparation of High Solid Content Waterborne Polyurethane by Special Physical Blending about?

This study presents the preparation of high solid content waterborne polyurethane (WPU-H) using a special physical blending method, combining small-particle (WPU-S) and large-particle (WPU-L) waterborne polyurethanes. The resulting WPU-H demonstrated a bimodal particle size distribution, achieving a solid content of 66.07% and a low viscosity of 285 mPa.s. Characterization techniques such as FTIR, DSC, and TEM were employed to analyze the properties of the different polyurethane samples.
