The most basic difference is that powder coating powder belongs to solid paint, and does not need solvents to spray;
water-based coatings are liquid coatings and require solvents.
1. Compared with water-based coating, powder coating powder is VOC free, theoretically 100% utilization rate, more environmentally friendly;
2 powder coating powder one-time coating thickness is generally 60~80U, liquid is difficult to do;
3. at present, the powder coating powder is mainly painted by charging way, so it is difficult to use in all substrates, and the metal substrate is mainly used at present; liquid doesn't have this limitation;
4. powder coating powder is difficult to achieve some of the surface effects of liquid coatings such as the mirror effect, even the best powder coating powder is difficult to avoid such defects as orange peel. So at present, powder coating powder is difficult to replace liquid coating completely.
