The powder of possibilities.
Uralac® Ultra by DSM: A proven powder coating technology for industrial coaters
Is it really possible to produce and apply a powder coating that brings the strength, reliability, aesthetics and cost-efficiency associated with metal applications…to engineered wood like MDF? At DSM we have the answer and it’s called Uralac® Ultra. This unique technology is more than just a resin: it’s a radical curing technology consisting of unsaturated polyester, a co-crosslinker and a thermal initiator. The result? Safe and sustainable powder coatings for MDF and engineered wood, applied in a unique single-layer process at just 120-130 degrees Celsius rather than the traditional 160-170 degrees Celsius. Already being used by numerous top companies, it gives industrial coating manufacturers a clear competitive advantage.

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.
