Frequently asked questions

How do we spray powder on standard 'non-conductive' MDF?

For application of the powder, moisture within the MDF is used for conductivity. A moisture content of 4-8% of total weight is sufficient to attract the powder. 

Do we require special MDF for powder coating?

No special MDF is needed for powder coating – although there are differences between available qualities and types.  

We advise evaluating the type of MDF you intend to use before making your products.  

Further, we recommend a conditioned storage area to control the MDF's moisture content. 

Is the oven I use for powder coating metal suitable for curing MDF too?

Most conventional curing ovens are convection ovens. Best results for MDF are reached with infrared radiation (IR) ovens.  

With IR ovens, the MDF's surface can be heated quickly to cure the powder coating, while its core stays relatively cool.  

With convection ovens, temperatures are often too high, or the MDF's core heats up too much because of the longer period needed to reach curing temperatures.
