| 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. |

| 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. |

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 |
