This coating segment is the domain of so-called Hybrid powder coatings represented by a combination of polyester resins with solid epoxy resins as hardeners. Excellent adhesion, flexibility, corrosion– and chemical resistance make them the first choice for all kinds of indoor applications for smooth, matte and textured finishes in all colors. But what to do when it comes to coating heat sensitive substrates like engineered wood and medium density fiberboards (MDF) at low temperature curing?

Can you powder coat wood and MDF?

In recent years, powder coating technology has been revolutionized. It can now provide the same high quality and environmentally friendly advantages for coating wood and other heat sensitive substrates, previously only possible for metal. Powder coating is a great option for certain types of wood products and MDF, due to the uniform surface and natural conductivity from its moisture content. As design ideas move away from typical shapes and flat edges, powder coating MDF offers the benefit of an even and durable finish on all shapes and contoured edges. This is perfect for modern office furniture, kitchen cupboards, bathroom cabinets and much more.

Can you powder coat plastic?

Powder coating temperature requirements have been one the technology’s main limitations. A few years ago, powder coating plastic would not have been possible as plastic could not withstand the heat. allnex is leading the way in manufacturing polyester resin for powder coatings to be applied at increasingly lower minimum temperatures. This opens the door to applications not widely used, including the possibility for successfully powder coating plastic.

The World’s leading powder coating resin manufacturers

allnex offers a full range of low bake hybrids suitable for single and double coat applications for a wide range of gloss levels, smooth and textured, for cure by conventional convection, or preferably, by infrared (IR) ovens. Find out more details from our product selection.

The vast majority of outdoor durable powder coatings is formulated by combining polyester resins either with triglycidylisocyanurate (TGIC, ARALDITE® PT 810) or β-hydroxyalkylamide (HAA, PRIMID® XL 552). Next to a balanced, good coating performance they are able to withstand 12 months of exposure to aggressive climates as in Florida. Modern resins allow the reduction of curing temperature to 160°C for PRIMID low bake powders; TGIC systems can even reach down to 120°C. Saving energy and increasing productivity by low temperature cure powders are not the only important aspects; a further added value is the fast cure of coatings on massive substrates. Our low temperature product portfolio will help you to identify the best option for your low bake powder project.
