MDF Powder Coating VS Liquid Coatings
| Economical | Environmentally friendly | Process limitations | Coating efficiency | Coating properties | |
| Powder coating | Low overall cost (coating + labor + energy consumption + storage), the overall cost of powder coating is 80-150 RMB/m2 | The construction environment is free of volatilization, odor, and sewage; the finished product is zero VOC and can effectively seal harmful substances in the board, which is healthy and environmentally friendly. The coating can be almost 100% utilized. | Can process special-shaped parts; convenient for processing chamfers and edges of plates, making products more beautiful and durable | Fast curing speed, simple process: 1-2 steps, construction time 2-4 hours, low storage space requirements | The coating has excellent performance, good resistance to chemicals and solvents, and can effectively block formaldehyde |
| Liquid coatings | Low overall cost (paint + labor + energy consumption + storage), the overall cost of liquid paint is 200-150RMB/m2 | High VOC, up to 31 kinds of chemical poisons volatilize, especially benzene, formaldehyde, aniline and diisocyanate toluene ester and other high-level substances. The effective utilization rate of the coating is low, and formaldehyde is released in the later stage. | The process is complicated, with 6-10 steps, and it cannot process special-shaped workpieces. It requires special edge sealing treatment in the later stage and is prone to cracking. | The process is complex, with 6-10 steps and 6-12 days of construction time, which requires a lot of manpower. The curing speed is slow and requires a lot of storage space. | The coating performance varies greatly depending on the type of product. It has poor water resistance, abrasion resistance and chemical resistance, and poor sealing performance against volatile substances such as formaldehyde. |
