Generally manufacturers produce the process is to use ordinary dry mix or use domestic bonding machine bonding powder. Such process does not achieve better results and is not stable in the spraying process.
Tiger powder like Taicang or Guangdong Huizhou Huili powder in this area are better, the use of imported bonding machine. But the corresponding powder price is also more expensive (basic 100 yuan / KG or more).
If you want a better result, you can cover the surface of the powder coating with a layer of transparent powder or paint. This is also mostly the method of construction by manufacturers.
The effect of paint relative to powder to be better, just now are considering the cost, so some manufacturers have begun to shift from paint to powder.
I hope the above reply is useful to you.
