MDF Powder Coating Line
VOC-free MDF and wood panel finishing — 20-minute total process
For furniture manufacturers, kitchen cabinet producers, and panel fabricators looking to switch from liquid paint or laminate to powder coating. Powder coating on MDF is a one-step, VOC-free finishing process — no solvents, no drying between coats, no spray booth ventilation requirements of liquid paint.

The MDF Powder Coating Process
The process from raw board to finished, touch-ready panel takes approximately 20 minutes:
- Preparation — sanding, cleaning, and moisture control of the MDF substrate
- Preheating — boards are heated to 40-85°C to improve powder adhesion
- Application — corona spray guns distribute low-cure powder in specialized booths
- Curing — 4-6 minutes at 105-130°C (significantly lower than standard metal powder coating)
- Cooling — conveyor cooling zone brings panels to handling temperature
- Unloading — panels are touch-ready immediately after cooling
Why Powder Coating on MDF
Compared to liquid paint, powder coating on MDF offers several operational advantages:
- One-step process — no primer coat, no drying between layers
- VOC-free — no solvents, no emissions, no spray booth air treatment requirements
- Scratch and humidity resistant — outperforms many liquid finishes in durability testing
- Antibacterial and hypoallergenic — relevant for healthcare and food industry applications
- EN 71-3 compliant — safe for children's furniture and toys
- Design freedom — powder coating handles complex shapes and rounded edges that are difficult with laminate
Applications
MDF powder coating is used for kitchen cabinet fronts and panels, bathroom doors, office furniture, TV units and media consoles, retail display fixtures, and architectural paneling. The finish is available in a wide range of colors and textures including matte, gloss, metallic, and wood-grain effects.
