1. excellent coating performance of metal powder coating
The coating has metallic luster, gorgeous multi-color effect and outstanding protection function, providing colorful appearance decoration for industrial products such as automobiles, household appliances, instruments and meters. As long as the powder coating is directly sprayed on the iron or aluminum materials with appropriate pretreatment, the coating surface with excellent performance can be obtained after baking, such as the durability of the coating, including abrasion resistance, impact resistance, adhesion, toughness, corrosion resistance and chemical resistance. In addition to the above advantages, outdoor powder coatings also include high weather resistance and pollution resistance.
2. metal powder coating reduces environmental pollution
Volatile solvents such as organic solvents and water are not used, so the powder coating is an inorganic solvent based coating, which greatly reduces the potential safety hazards caused by solvents.
Powder coating is a 100% solid powder coating, which can be fully automatically sprayed. The metal powder coating has almost 100% utilization rate, which makes the coating industry reduce the disposal of waste and reduce the degree of environmental pollution to.
In most cases, the electrostatic spray gun is used for spraying. Since this type of product contains metal pigments, it is necessary to ensure the good grounding of the system when using the electrostatic gun for spraying, and set a low electrostatic voltage and powder output to prevent ignition during spraying. The effect of forming the coating film has a great relationship with the setting, quality or brand of the spray gun. After long-time spraying, a large amount of metal powder may accumulate at the discharge needle of the spray gun, and the sprayer needs to clean the discharge needle regularly.
