Powder coating is the durability of good varieties, the appearance of film as solvent coatings. In general, the smaller the particle size of powder coating, the beautiful appearance of the better, but small average particle size of powders in a painting, construction efficiency will drop. The product is to solve so far powder coating cannot both film aesthetics and painting of issues of economic development and the particles of powder coatings, the average particle size than previous powder coating fine, size deviation is less than 20�� m rank complete. Therefore, powder particles can be coated with concave uniform attachment, can get appearance smooth coating, and coating than the general powder coating thin, so the use of coating quantity is less, can reduce coating cost. The film appearance quality and solvent resistance coatings of the same, it could be expected for a portable telephone, personal computer and other information technology equipment, household appliances, office machinery, landscape materials, can also be used with the requirements of the surface coating of beauty products. Expected size under 20 �� m fine powder coatings to be practical, but on this occasion, particle size less than 5 �� m ultrafine powder content a, coating construction line will be extreme worsening, powder coating recyclable reuse advantages have all gone, the company developed to solve this problem new powder coating also patented, its characteristic is the average particle size in the range of 5-20�� m, 5 ��m following ultra fine particle content of no more than 25%.

China powder coatings particle size in the 10-80 micron, the thickness of the coating is in more 50-70 microns. To thin coated 20-30 micron, particle diameter in the 10-50 micron. But increased powder production difficult.
