Problems solved by technology

[0003] The polyester powder coatings in the prior art do not have conductive properties, so that the surface resistance of the coating film is relatively high, and it is easy to be charged with static electricity, and the generated static electricity is difficult to leak for a while, causing the static electricity to accumulate
Based on this characteristic, the use of polyester powder coatings in many occasions is likely to cause fire, explosion and other hazards, thus limiting its application fields
