As a post-process of the processing of the wooden door factory, its advantages and disadvantages directly affect the final use effect. At the same time, the cost of paint is also one of the largest parts of the cost of wooden doors.
The types of paints are broadly classified into phenolic paints, alkyd paints, polyurethane paints, nitrocellulose paints, polyester paints and PU paints. Among them, phenolic paint and alkyd paint are basically eliminated in the decoration due to the poor texture and adhesion of the paint film. A large number of PU paints used in lacquer, polyester paint and high-grade furniture are used. Due to the simple construction and suitable for manual operation, the nitrocellulose lacquer is used by most hand-decorated woods, but its paint film is thin, the hand feel is not good, and the effect is not satisfactory.
Due to the cost processing methods and equipment problems, 90% of the wooden doors on the market use polyester paint, and a few manufacturers use PU paint. In general, polyester paints and PU paints have to go through six processes, such as color finding, three bottoms and two sides. Some brands increase the curing and waxing process.
Therefore, paint is one of the factors that must be considered when choosing a wooden door. It directly affects the texture, feel, moisture, environmental protection, durability, and yellowing resistance.
