Frequently asked questions
For the application of the powder, the moisture in the MDF is used for conductivity. A moisture content of 4-to-8 percent of weight is sufficient to attract the powder.
No special powder-MDF is needed for powder coating – although there are differences between the available qualities and types. We therefore recommend evaluating the MDF type you intend to use before making your pieces. Furthermore, a conditioned storage area is recommended to control the moisture content of the MDF.
Most of the conventional curing ovens are convection ovens but the best results for MDF are reached with infrared radiation (IR) ovens. With IR ovens, the surface of the MDF can be heated up quickly to cure the powder coating, while the core of the MDF stays relatively cool. With convention ovens, the temperatures are often too high or the core of the MDF heats-up too much because of the longer time needed to reach the curing temperature.
