Compared to the traditional liquid coatings, the advantages as follows:
Powder Coatings:
1.Just need one coat.
2.It can be recycled, utilization rate is 95%.
3.Without solvents and Volatile organic compounds,environmentally friendly.
4.It's inexpensive.
Traditional liquid coatings:
1.It need 2-3 coats, include primer, varnish,Colored paint etc.
2.It can not be recycled, utilization rate is 30%-50%.
3.It's solvent type, as high as 50%-70% solvent evaporation.
4.It's costly.

Construction requirements :
If your are currently using powder from someone else , or you are currently using our powder but different color specie, you must have your painting system completely clean before the job, that will keep you away from powder messing up and kind of failed coating or color defects by pollution issue.
1,Keep your device and work environment clean to go, that will prevent large particle to show up on coating by avoiding dust going in.
2,Recycled powder would pass through filter mesh 140 before the job
3,Workpiece must perfectly pass through pretreatment stage to make sure no residue left but that phosphate film ready to go, no grease, no rust,nothing left to fail adhesion force.
4,Electrostatic gun will have shoot voltage shift from 50kv to 90kv,Gives excellent atomization work, and spray powder equally like a even work.
5,Target Temperature 200±5ºC(workpiece temperature) 10 minutes will do curing job, do over limit would make your coating poor as far as you do.
6,Make sure your ventilation and static ground work well, so pollution will be limited in control and worker will be secured.
