Polyurethane Paint/Polyurethane Coatings Manufacturer Direct Sales/Paint Ordering - Mr. Liu: 186^0280^5638; Supply available in Sichuan, Chengdu, Yunnan, Chongqing, Guizhou, and other regions. Polyurethane paint is a coating with polyurethane resin as the main film-forming substance. Its paint film is hard and wear-resistant, with excellent chemical corrosion resistance, oil resistance, and water resistance. It features high gloss and good gloss retention, widely used in furniture, flooring, automobiles, machinery, ships, and other fields.

Potential issues during the application of polyurethane paint:
Slow drying of the paint film: This may be due to high environmental humidity, low temperature, or improper selection of thinner, which hinders solvent evaporation. It is necessary to control the application temperature and humidity (recommended temperature ≥15°C, humidity ≤80%) and choose the appropriate thinner.
Wrinkling of the paint film: Caused by thick coating or applying the topcoat before the underlying layer is fully dry, leading to uneven solvent evaporation and shrinkage. Follow the principle of "thin coats, multiple layers" and ensure each layer is dry before applying the next.
Bubbles/Pinholes: Result from air introduced during stirring or high moisture content in the substrate. Allow the paint to sit to eliminate bubbles before application, and ensure the substrate is dry (moisture content <8%) and clean.
Poor adhesion: Caused by insufficient sanding of the substrate or the presence of oil, dirt, or moisture on the surface. Thoroughly sand to a rough surface and clean it. Using a compatible primer can enhance adhesion.
Strictly follow the product instructions before application, properly prepare the substrate, and control the environment to minimize issues.
