Coating method of metal powder coating

Friction spray guns are generally not suitable for spraying metal powder coatings. In most cases, electrostatic spray guns are recommended for application. Since this type of product contains metallic pigments, when using an electrostatic gun for construction, ensure that the system is well grounded, and at the same time set a lower electrostatic voltage and powder output to prevent ignition during spraying. The effect of forming a coating film has a great relationship with the setting, quality or brand of the spray gun. After spraying for a long time, a large amount of metal powder may accumulate at the discharge needle of the spray gun, and the applicator needs to clean the discharge needle regularly.
