Ceramic materials have played pivotal roles in shaping civilizations, from ancient pottery vessels to modern technological advancements. Up to this day ceramics are indispensable for some industries due to their unique combination of properties like heat resistance, electrical insulation, chemical durability, and mechanical strength. When talking about aesthetics however, there are things to be improved – improvements that can be made with powder coating!
Powder coating ceramics is a specialized powder coating technique of applying powder particles onto a ceramic surface. It is a different process compared to standard powder coating applications, as unlike traditional substrates like metal, ceramic is not a good electric good conductor.
But, while that’s all well and good, why powder coating over traditional finishes like ceramic glazes, you may ask? It is just an alternative for visual enhancement or is there more to it? Well, powder coating offers improved durability and abrasion resistance, that regular ceramic finishes cannot.
So, how are ceramics powder coated? Like glass, wood and plastics, ceramics do not conduct electricity. That’s why in this case coaters must look for alternatives to the “traditional” Tribo- or Corona application methods. In practice manufacturers rely on hot coat application, where to substrate is heated enough for the powder to gel and therefore stick to the object. One thing to look out for here is outgassing of the substrate. In theory, methods like conductive pretreatment (e. g. TIGER Static Fluid) could also work for these applications.
Powder coated ceramics are most often found with flowerpots. Aside from aesthetics powder coating here also provides abrasion resistant surfaces, which are especially important considering that these objects are often moved and stacked on top of each other. While the most common this is however not the only decorative application possible!
All in all, powder coating on ceramics is a fantastic alternative to traditional glazes to not only change things up visually but also improve several functional capabilities of the ceramic surface.
