Abstract
Waterborne Polyurethane Dispersions with Enhanced Hydrophobicity for Direct to Metal Application
Co-author: Szuping Lu

Polyurethane dispersions (PUDs) has been found in many high performance water-based coatings due to excellent properties and weatherability. Considerably attempts have been made to improve corrosion resistance and mechanical properties through polymer structure and composition engineering to provide a robust system for direct-to-metal (DTM) application. In this work, by incorporating hydrophobic building blocks and structural design of waterborne PUDs results in excellent anti-corrosion performance and water resistance compared to conventional PUDs. In addition, an adhesion study on cold rolled steel (CRS) by peeling strength will be presented and compared to industrial DTM water-based resins, and water absorption and early water resistance will also be evaluated.
