The new surface coating technology in door finishing plays a crucial role in determining the quality grade of wooden doors, especially as the Chinese wooden door industry continues to grow. Currently, the market still faces challenges in meeting the demand for both quantity and variety. Choosing a wooden door is not just a functional decision—it's a personal statement, reflecting one's lifestyle and appreciation for comfort and aesthetics. As China's economy continues to develop, people's quality of life is improving, leading to higher expectations for home products. This trend brings significant business opportunities for the wooden door industry. The key challenge for companies now is to guide consumer preferences by offering eco-friendly, attractive, and cost-effective products.
It is expected that the market will place even greater emphasis on the overall quality of wooden doors, particularly in terms of their finish and durability. A well-executed paint job can serve as a major selling point, making it essential for manufacturers to focus on improving their coating processes. According to recent surveys, some wooden door companies still have room for improvement in their painting techniques. While products may look good from a distance, closer inspection often reveals issues like orange peel texture, sagging, hairiness, or poor definition. These problems can significantly impact consumer perception and satisfaction.
Currently, most wooden door manufacturers use polyester coatings (also known as PU coatings) for both primer and topcoat applications. This method is widely accepted due to its maturity and reliability. From a furniture industry perspective, PE-based primers offer several advantages, such as high solid content, excellent coverage, and the ability to apply thick coats in a single pass. They dry quickly, are hard, easy to sand, and produce less oozing. Their high-quality performance, low consumption, time efficiency, and environmental benefits make them superior to traditional PU primers.
While PU transparent primer is commonly used, for more demanding products, we recommend using PE transparent primer as the base. Under the same process, the surface finish and stability of the product are significantly better than those achieved with PU primer. This is due to the unique properties of PE paints, which offer superior hardness, resistance to sagging, and high solid content.
PE paint has a hardness of up to 5H, compared to only 2H for PU paint, which typically reaches 1H. This difference in hardness makes PE paint much more resistant to sagging. Additionally, PE paint is a high-solid coating, with solid content exceeding 90%, while PU paint usually has less than 50%. This means that, under the same spraying conditions, PE paint produces a much thicker and more durable film.
Considering cost, processing methods, and equipment limitations, the majority of wooden doors on the market today use polyester paint, with only a few manufacturers opting for PU paint. Both types of coatings typically go through six steps, including color matching, three layers of primer, and two layers of topcoat. Some brands also add curing and waxing processes. Therefore, the choice of paint is a critical factor when selecting a wooden door, directly influencing its texture, feel, moisture resistance, environmental friendliness, durability, and resistance to yellowing.
