The powder of possibilities.
Key benefits of powder coating
With its smooth surface ideal for painting and attractive price point versus plywood, it’s no surprise that demand for MDF and similar engineered woods is growing. Finishing for MDF board and panels has traditionally involved liquid paint because of the extreme 150-plus degree Celsius temperatures needed to cure powder coatings and melt them onto the surface. In turn this extreme heat load made the board more likely to crack, bubble and pop as the material’s fibres are warped and raised up in the heat. But now, thanks to advanced technologies like Uralac® Ultra, powder coating really is the best way to finish paint, both for brands and coating specialists alike. Why? Because the key ingredient - the resin that binds the paint together – enables a curing temperature as low as 120 degrees Celsius. This in turn opens up a whole new world of engineered wood possibilities by enabling bold and beautiful new designs (in furniture, for example) that delight consumers. It’s MDF time…

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.
