Ten times faster with powder coatings
Powder coatings are more scratch-resistant, more humidity-resistant, and offer good chemical resistance, while at the same time providing excellent surface appearance with a range of gloss levels.
"We also found that architects were particularly interested in the product's very low carbon footprint,'' says Laureyssen. "This characteristic helps architects achieve more 'green' credentials in their proposed tenders for local and national government new builds."
Why is powder coating so fast?
"Powder coatings are faster to process than liquid paint because there is no priming and less sanding involved," says Kempa owner Maeyninckx. "There's also a reduced curing time. So you can see why it is ten times faster – especially for single-coat processing. But make no mistake, this increased speed does not impact quality at all."
Frequently asked questions
How do we spray powder on standard 'non-conductive' MDF?
Do we require special MDF for powder coating?
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.
