How to paint iron sheet

Self-drawing can be used to draw iron sheets. Self-painting is widely used. Through the economic development in recent years, its application has developed from repairing paint defects at the beginning to various industries such as molds, industrial machinery, toys, handicrafts, musical instruments, architecture, steel structure, advertising, signs, graffiti and so on. Even in grassland pastoral areas with low industrialization, self-painting is adopted. It is said that the self-painted colors are used to distinguish the cattle and sheep of various farmers.

There is no strict classification standard for painting, and the usual classification method is to classify according to people's usage habits. Generally, according to the types of main film-forming substances in aerosol paint, it can be divided into nitro aerosol paint, alkyd aerosol paint and thermoplastic acrylic aerosol paint. And there are ordinary inkjet, metal flash inkjet, fluorescent inkjet, super metal inkjet, chrome inkjet, gold inkjet, hammer inkjet, high temperature inkjet and so on.

Thermoplastic acrylic resin coating dries quickly at room temperature and is easy to use. Its solid effective component content and hiding power are better than nitro enamel, but its gasoline resistance is poor, so it is not suitable for spraying equipment that comes into contact with gasoline or organic solvents, such as cars and motorcycles. Mainly used for indoor and outdoor decoration engineering, mechanical equipment and plastic surface decoration.
