Abstract: ［Objective/Significance］This paper aims to analyze the current status of industrial R & D of waterborne polyurethane coating resins and prospect its future development trends.［Analysis/Discussion/Progress］Through a systematic analysis of the commercial product lines andproduct iteration histories of leading global companies，the current status of industrial technology in this field was deeply explored. Based on the classification system of commercialized WPU resins，the industrial technology development progress and practical application scenarios were discussed indetail，focusing on four dimensions：thermoplastic，self-crosslinking，hydroxyl-functionalized，and radiation-curable WPU resins.［Conclusion/Prospect］The industrial R & D of WPU coating resins exhibits highly pragmatic characteristics，with low-carbon，eco-friendly，and high-performance orientations serving as the core development directions.

Key words: waterborne polyurethane, self-crosslinking, oil-modified, UV-curing, waterborne 2K coatings
