Problems solved by technology

There are two types of wood grain transfer printing on aluminum profiles: electrostatic spraying and electrophoresis. Among them, the method of electrostatic spraying is to coat a layer of thermosetting organic polymer powder on the surface of the aluminum profile, and after high temperature curing, a certain permeability is formed on the surface of the profile. Compared with the electrophoretic coating surface treatment method, it is environmentally friendly, the mechanical properties of the coating film such as hardness, wear resistance, impact resistance and other indicators are high, and the service life is long. The advantage of rich colors has become a hot spot in the surface coating of aluminum profiles in China. However, the aluminum alloy wood grain transfer profiles obtained by this method often have the defect of poor weather resistance, which limits its application.
