We had used powder coating process instead of spray painting process

After a period testing, we feel powder coating is superior to paint and is the best choice in terms of price and quality.

Spray painting is a painting technique where a device sprays a coating (paint, ink, varnish, etc.) through the air onto a surface. Powder coating is a type of coating that is applied as a free-flowing, dry powder. Spray painting and powder coating are both organic coating processes, so they'll be wear and tear by natural means. Sunlight, moisture, and oxidation are all possible over long periods of time, as are physical defects such as flaking or peeling.

There are many advantages to powder coating our products over applying regular spray painting, such as lower cost, better performance. But the most important is that Powder coating is more environmentally friendly than traditional liquid painting due to the powders being cured in an oven and therefore emitting zero VOCs.

The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating generally produces a coating twice as thick as standard paint. The real advantage is its flexibility and ability to bend and yield with the material it is applied to.

But one important down sides of the powder coating is that it can be difficult to match metallic paint colors.

Anyway, we will try our best to update our process to make our signage products better and better.
