wood and mdf frames ready for powder coating

Powder Coating Wood & MDF

Wood and wood composites are both excellent substrates for the UV-cured powder coating process. UV-curable powder coating uses significantly less heat and has a very fast processing time. This is beneficial because the longer wood is exposed to heat the more it degrades, causing defects such as cracking, outgassing, pin holing, grain raise, and fiber popping.

UV-curable powder coating can be a one or two coat process depending upon the finish requirements of the customer. Even a two coat UV-cured powder coating process is faster than alternative finishing processes.

Applications for powder coating wood and wood composites include: retail and POP fixtures components, shelving, commercial and residential furniture, and healthcare components to name a few.
