Uralac® Ultra: The key benefits of powder coating.

Covestro's Uralac® Ultra is an innovative binding technology for power-coated MDF that delivers a variety of benefits in performance, efficiency, sustainability and cost.

With its smooth surface, ideal for painting and attractive price point versus plywood, it is no surprise that demand for MDF and similar engineered woods is growing.  

Finishings for MDF boards and panels have traditionally involved liquid paint because of the extreme >150°C temperatures needed to cure powder coatings and melt them onto the surface. In turn, this extreme heat load made boards more likely to crack, bubble and pop as the material's fibers warped and raised up in the heat.  

Now, thanks to advanced technologies like Uralac® Ultra, powder coating really is the best way to finish paint, for brands and coating specialists alike. Why? Because the key ingredient – the resin that binds the paint together – allows for curing temperatures as low as 120°C. This opens up a whole new world of possibilities for engineered wood by enabling bold and beautiful new designs – in furniture, for example – that will delight consumers. It is MDF time!

"We believe that powder coating technology has reached the level of sophistication where we want to use it."

Expand your horizons

How do brands find imaginative ways to create a competitive advantage in the race for innovative new products? One way is to swap liquid-coated MDF for a powder-coated solution based on Uralac® Ultra.  

This advanced binder made from unsaturated polyester enables powder coatings to be produced up to 10 times faster than waterborne equivalents, with the most complex designs, including hollows, contours and edges – unlike traditional UV-cured coatings. All with a solid, seamless finish produced via a unique single-layer coating process that requires just one application of sanding and is cured at an all-time low temperature.  

Uralac® Ultra saves you time and money, and it helps preserve the planet with a carbon footprint 5 times lower than traditional coating systems. It is safer, solvent-free, and does not contain harmful VOCs.


Coatings for when the going gets tough

Uralac® Ultra is an advanced binding technology that takes durable coatings and protective finishes to a new level in powder. Made with a super-strong polyester-urethane binder, this hard resin resists extreme wear and tear like scratches, abrasion and UV, with no yellowing or peeling: all with extreme flexibility.  

Uralac® Ultra has passed a range of industry tests – including NEN-EN 12720, Blue Wool Scale, and hinge hole (Ledro test) benchmarking. 



Start reducing your costs today

Powder coating systems with Uralac® Ultra at their heart can reduce your production costs by up to 45% compared to liquid coatings. Thanks to low curing temperatures and a unique single-layer coating process, the product requires less water, energy and time to produce; and there is less waste – with powder overspray being almost 100% recyclable.  

With no sanding required between application of layers, you generate yet more savings in time and materials. The result? Customers have produced their coatings up to 10 times faster using Uralac® Ultra-based systems as compared to liquid paint. In fact, Uralac® Ultra even saves you money during storage and transportation thanks to its high chemical resistance and overall robustness compared to conventional coating solutions. So jump aboard! 

"We're always looking for ways to reduce costs without impacting quality. Fortunately, these powder coatings deliver on both."

我们如何在标准“非导电”MDF 上喷涂粉末?

对于粉末应用,MDF 内的水分导电作用。占总重量 4-8% 的水分含量足以吸粉末。

使用粉末涂料是否需要特殊 MDF?

粉末涂料不需要特殊 MDF–尽管现有 MDF 的质量和类型之间存在差异。

我们建议在制造产品前评估您打算使用的 MDF 类型。

此外,我们建议将其储存在恒温恒湿区域以控制 MDF 的水分含量。

用于金属粉末涂层的烘箱是否也适合固化 MDF?

大多数传统固化烘箱都是对流烘箱。使用红外辐射 (IR) 烘箱可以获得 MDF固化的最佳效果。

使用 IR 烘箱,MDF 的表面可以快速加热来固化粉末涂层,同时其核心则保持相对较低的温度。

使用对流烘箱时,温度通常过高,或者由于达到固化温度所需的时间较长,导致MDF 的核心温度过高。

"There are many benefits to powder coatings. First and foremost, they are totally toxin free."
