Ultrafine Powder Coatings Technology FineShinePowderTM

        Ultrafine Powder coating technology is a unique patented technology of Fineshine. This is the first case in the world where the conventional powder coating has been successfully reduced down from 30-50 microns in size to about 15 microns, achieving liquid coating like smoothness.

 
Traditional coarse powder particles have an average grain size of 40 microns Ultrafine Powder particles have an average grain size of 17 microns
   
 
Coarse powder coatings before curing   Normal powder coatings after curing
Coarse powder has a large grain size and requires a large spray amount before the curing process. In particle form the surface is fairly non-uniform. Even after curing, the surface results remains relatively uneven compared to liquid coatings.
 
Ultrafine Powder coatings before curing   Ultrafine Powder coatings after curing
Ultrafine powder has a large grain size requiring a lowered spray amount before the curing process. In particle form, the surface is fairly uniform. After curing, the surface is relatively even compared to liquid coatings.

The coarse powder with an average grain size is 38.8 microns forms a coating with a film thickness of 75 microns
Experiment results indicate a surface roughness of 16,786 A
  The Ultrafine Powder with an average grain size is 17 microns forms a coating with a film thickness of 30 microns
Experiment results indicate a surface roughness of 2,613 A

    1200h salt spray corrosion experiment comparison pictures
Experimental evidence shows that the corrosion resistance of the 40 micron thick Ultrafine Powder coating is superior to that of the 60 micron thick coarse powder coating
Products sprayed with Ultrafine Powder form a thin film and a very smooth surface
