method stands to be different from other two, because it is found to have more highlighting features than the other two. Now, while talking about this powder coating method many has doubts regarding this process. But is a simple process which involves in spraying the paint which is electro statically charged. In liquid paint there will be in need of solvents but here in powder coating method solvents are not necessary. Hence it gives a finite result at the end when compared to the other to painting methods. Now let us see the step by step process of Powder Paint Coating on Aluminum in detail.
Aluminum surface has to be pre – treated
Pre – treating the process helps to clean the dust and all other foreign particles found accumulated on the surface of the layer. Pre – treating will prevent flaking defects and so it will be very first process which has to be carried out before indulging in powder paint coating on aluminum process.
Application of the powder
The next step is that the technician will now start spraying the powder on to the surface with the help of electrostatic gun. Gun produces positive charges and then the powder will bond equally upon the surface which is cleaned.
The next come the heating process and here the professionals place the extrusion on the curing oven. After that the oven starts baking the extrusion until the desired or uniform coating is obtained.
After completion of heating process the next will be to cool the extrusions and once it is cooled the coating gets hard and the desired result can be obtained.
While using the method of powder paint coating on aluminum there are numerous advantages and few are stated here,
- Varieties in giving beautiful colors
- Very good to environment than the use of liquid paint
- Sticks firmly to the aluminum
- No need to worry about chipping or peeling defects
- Financially affordable
- Available in all places
- Long standing life
These are the common features which are said to be more alluring in this powder paint coating on aluminum. The look of aluminum is enhanced after finishing this process as it will look brighter, beautiful and the texture will be smoother than the original one. Hence it is the good choice to get the desired result quickly.
