Advantages of Coil Coating

1. High-Precision Coating
During the process of coil coating, the roller requires clean and smooth material surface.

2. Evenly Coating in High Degree
Because the roller itself is manufactured in a high-precision degree with a tolerance no more than ±1∪m, thus, the coating it produces obtains a high degree of evenness, and the tolerance of thickness is between ±1∪m. 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. Besides, although the pigment will gradually fade inevitably after a specific period due to the weathering, the color still looks uniform. That is, the pigment will fade in a unitive pace but the color difference caused could be ignored. However, for other coating methods like spray-coating, the effect of evenness and color difference is not as good as that of coil-coating. For example, the tolerance of color difference of spray-coating is usually between ±5∪m, sometimes ±10∪m, which will create a very disorderly color scheme to the finished curtain wall.

3. More Advantages of Coil-Coating in Metallic Painting
Presently, metallic color coatings become more and more popular and are gradually accepted 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
As on paint fog is produced in the process of coating, the efficiency of paint is very high. For spray-coating, it will produce paint fog, which not only contaminates the environment but also wastes the expensive paint.
ALUTILE Composite Curtain-Wall products all adopt coil-coating. We have two sets of advanced coil coating production lines.
