ROLLER COATING VS SPRAY POWDER |
|
Roller Coating Printing Ceiling/High Polymeric Ceiling |
Traditional Spray Powder Ceiling |
Surface Smoothness |
Roller Coating/Polymer is a compression printing coating, the entire coating film and the surface of non-granular and non-porous |
Spray powder is an electrostatic floating coating, the entire coating film and the surface is the accumulation of particles and micropores |
Dust resistance |
Due to the coating layer and the surface of non-granular and non-porous, pollutants can not penetrate the surface |
Due to the coating layer and the surface for the accumulation of particles and microporous, contaminants easily penetrate the surfae to the coating layer |
Density and Abrasion resistance |
Roller Coating/polymer finish should painting twice and baking twice, the coating is non-granular |
Spray powder finish should painting twice and baking twice, the coating layer is the accumulation of particles |
Coating thickness |
Due to plate compression coating, board uniform force, film thickness error is less than 0.5 |
Due to electrostatic floatation coating, the surrounding and the middle coating uneven, film thickness error of about 7( one of the factors caused by color |
