The Advantages of Coil Coating

1¡¢ High-Precision Coating
The roller has high requirement for the material surface, which means it should be absolutely clean and smooth during the process of coil-coating.

2、 Evenly Coating in High Degree
Because the roller itself is manufactured in a high-precision degree with a tolerance no more than ¡À1¦Ìm, thus, the coating it produces owns a high degree of evenness, and the tolerance of thickness is between ¡À1¦Ìm. Also, during the process of coil-coating, all the stress is applied in an even and stable way, which makes coating's microcosmic array be uniform in all aspects. As a result, the visual effect of curtain-wall will become perfectly uniform due to the assemblage of plenty of panels with such coatings. Another important thing is, although the pigment will gradually fade inevitably after a specific period due to the weathering, the color still looks uniform. In other words, the pigment will fade in a unitive pace and the color difference caused could be ignored. However, for other coating methods like spray-coating, the effect of evenness and color difference is far from that of coil-coating. For example, the tolerance of color difference of spray-coating is usually between ¡À5¦Ìm, sometimes ¡À10¦Ìm, which will create a very disorderly color scheme to the finished curtain-wall.

3、 More Advantages of Coil-Coating in Metallic Painting
At present, the metallic color coating become more and more popular and is gradully recognized by most of customers. Also, the metallic color pigment is created by adding metallic powder to the resin. Due to the special shape of metallic powder such as polyhedron, only through the coil-coating method, it could be converted and as a result, evenly and regularly distributed in the resin. However, if adopting the method of spray-coating, the metallic powder will always stay on the top of resin, which will make the resin coating very thin and easily to be corroded.

4¡¢Environmental Protection
Because coil-coating technics will not produce paint fog in the process of coating,the efficiency of paint is very high.For spray-coating,it will produce paint fog,which not only contaminate the environment but also wastes the expensive paint.
