The Look and Shape of the Future: Powder Coated Wood

Key takeaways from this article:

Your designs no longer need to be limited to shapes that can be edge banded. Powder coating flows easily over curves, edge profiles, cutouts, embossed images, and branding that have been routed into the MDF. Get curvilinear with your design and enjoy the benefits of this durable, consistent finish option that is powder coated MDF.
Do you have a RAL, Pantone, paint, laminate, or fabric you’re looking to match? Powder coated finishes offer exact color matching in reasonable quantities. Achieve metallic looks such as silver, chrome, gold, copper, and platinum. Tinted clear and multi-color that can mimic solid surface are also options. Not only are your color choices nearly endless but you can also specify textured to smooth, and gloss ranging from matte to high gloss.
Now that you’re up to speed on the look of powder coated wood products, let’s talk about why you would select them when a green and healthy finish is necessary. Powder coated finishes do not contain any VOCs or dangerous chemicals. The MDF can be fully recycled and is formaldehyde-free, which can contribute to USGBC LEED points. An antimicrobial additive that prevents the spread of bacteria on the surface can be added to the powder. Further, the finish is seamless so it doesn’t leave any crevices for bacteria to hide.
The future is now, and powder coated MDF components make a great fit for many applications. Consider them for your next project.

The Look and Shape of the Future: Powder Coated Wood

The future is often hard to predict, but one thing is certain — powder-coated wood has the look and shape that designers and architects will use to define quality and a health conscious lifestyle of the future.
Powder coating involves the use of an electrostatic charge, both positive and negative, which offers tremendous adhesion in the bond and incredible strength. The process of powder coating metal has been around for many years. Metal has properties that make it a good conductor of electricity; whereas wood does not. Powder coating on metal was quickly accepted into the market, but powder-coated wood has taken longer to master due to this challenge of electrostatic conductivity. MDF has now been custom formulated for powder coating with approximately 8 percent moisture content. The powder-coating process requires heating the MDF prior to coating to bring the moisture to the surface; as a result, this moisture serves as the source of electrostatic conductivity.
Powder-coated wood is capable of producing some of the highest quality and extremely durable wood finishes. The process of powder coating on MDF requires substantial investment in technology, equipment and expertise. The future is now for a preferred wood finish whenever the requirement is for durability, moisture resistance, chemical/stain resistance — or where the benefits of green are desired.
This type of finish is gaining popularity throughout Europe, and most recently growth in the United States has been led by companies such as Herman Miller (office furniture) and ClosetMaid. The goal: to produce a finish that exceeds the performance specifications of liquid finishes and many HPL laminates.

Unlimited shapes

Powder-coated wood is limitless in terms of designing shapes and profiles when compared to HPL laminates because there is no need for edge banding. When manufacturers want to use curves, elegant edge profiles, cutouts, embossed logos or contoured surfaces, then wood is a great choice because of the design flexibility. The final product gives a consistent, professional and customized look.
With our advanced application techniques and equipment, BTD Wood Powder Coating can handle materials of any size and shape.

The biggest challenge for powder-coated wood to overcome lies with designers and architects who limit their use of curvilinear shapes for those shapes that are designed to work primarily with melamine and HPL laminates. It is only a matter of time before architects and designers understand the innate qualities and features of this type of durable, consistent, brilliant finish.

Powder-coated wood provides a very upscale, elegant appearance, such as high gloss black similar to a baby grand piano or metallic silver.

Unlimited colors and textures

Whether you seek to achieve RAL or PMS colors or you have a sample colored HPL laminate, wallpaper or specific fabric, powder coatings can be matched to give you a color coordinated look that can be carried throughout your project. Metallic colors such as silver, black chrome, gold, copper, platinum and brass are available in powder. Plus, these metallic colors, when combined with other colors, provide a hammertone appearance which is very appealing in today’s fashionable color palettes. If you prefer a more traditional stained finish, powder-coated wood provides choices such as cherry, walnut, maple or whatever variation of stain color preferred, yet it can be more durable than what a liquid finish would yield.
What about a multicolor look, such as a splash of spackling on black, white and gray or any other combination of colors to give that multicolored appearance? Is your preference for the look of a solid surface such as granite? No problem; you can have it, and better yet, you can get it in a smooth or textured finish depending upon the final look you want to achieve. Is slate your style? Do you want blue, black and gray? Create whatever color you can dream up.
Another choice is whether you want a matte or glossy finish. For example, do you like that beautiful black glossy finish of most baby grand pianos? It can be accomplished for your project as well.
Because powder coating on wood is applied using a 5 to 8 mil thickness as compared to a liquid finish that is typically less than 1 mil thick, it creates a thicker and more durable finish for longer longer life and use of the product.

Green and healthy lifestyle

A great feature of powder-coated wood is that it has no VOCs or dangerous chemicals. Plus, because powder coating totally encapsulates the part, there is no need to use PVC edge banding, which poses many health concerns and is currently experiencing growing public pressure to be eliminated.

MDF manufacturers, such as SierraPine, use recycled board and have formulated a formaldehyde free board for the marketplace. SierraPine uses recycled material so it is very green friendly, and in construction projects, this is great for obtaining LEED points with the U.S. Green Building Council (USGBC).

There is an antimicrobial additive that can be used in the powder that is patented by DuPont. It can be used in the powder which prevents the spread of bacteria on the powder-coated surface because it removes 99.9 percent of the surface bacteria with active ingredients that last for many years. Plus, the finish is seamless with no crevices for bacteria to hide and foster. This additive is a great option for surfaces used in healthcare, day care, schools or any environment where bacteria can be a threat and surfaces come in contact with humans.

The Future is Now

Some things in life are predictable, and the rapid growth of this great finish is one of them and has been perfected by a few industry leaders. It is expected these leaders will pave the path to the future.
