To improve the construction performance of water-based polyurethane, consider the following methods:  1. Adjust the formulation: By modifying the proportions and types of raw materials in the formulation, you can enhance the film-forming properties, drying speed, and water resistance of water-based polyurethane.  2. Optimize the construction environment: Ensure a dry and clean construction environment while controlling temperature and humidity to avoid adverse effects on performance.  3. Add additives: Incorporate appropriate additives, such as leveling agents and defoamers, to improve the construction performance of water-based polyurethane.  What other methods do you know?
