The types of paint are roughly divided into phenolic paint, alkyd paint, polyurethane paint, nitrolacquer, polyester paint (PE paint) and PU paint. Among them, phenolic paints and alkyd paints are basically eliminated during decoration due to poor texture and adhesion of the paint film, and a large number of nitrocellulose paints, polyester paints, and PU paints are used.
Because nitrocellulose lacquer is relatively simple and suitable for manual operation, it is used by most of the hand-decorated wood to make it thin. It has a poor feel and the effect is not ideal. The advantage of PU lacquer is that it is easy to polish and it saves time and effort in the process. The disadvantage is that the paint film is soft, and light shadow bumps can easily produce white shadow dents. If at least one layer in the lacquer layer is a PE lacquer, this will be greatly reduced. The advantage of PE paint (polyester paint) is that the paint film is hard, the hiding power is strong, the transparency is good, and the veneer texture can be expressed better. The disadvantage is that it is difficult to polish, the processing process is time-consuming and laborious, and most manufacturers do not want to use PE coating.
At present, 90% of packaged wooden doors on the market use polyester paint, and a few manufacturers use PU paint. In general, polyester paint and PU paint have to look for color, three steps and two sides and other six processes, some brands increase the curing and waxing process.
Therefore, in the selection of wooden doors, paint is one of the factors that must be considered. It directly affects the texture and feel.
