What is Power Coating?

Power coating is a dry finishing process, using finely ground particles of pigment and resin, which are electrostatically charged and sprayed onto a part to be coated. The charged particles adhere to the parts until melted and fused into a tough, even coating through the application of heat and energy.

Some woods and wood products such as MDF have sufficient and consistent moisture content to provide conductivity and can be coated directly. Wood parts that require sanding can be cleaned with compressed air to remove any surface contaminants. To enhance electrostatic attraction, wood can be pretreated with a spray solution that provides a conductive surface. The part is then preheated to a desired coating temperature, which softens or partially melts the powder when it is applied and helps the powder adhere to the part where it melts a little on impact. A uniform board surface temperature allows for high transfer efficiency and a consistent appearance.

Powder coating is revolutionizing the MDF market because it offers design freedoms other finishing methods and laminating processes just cannot provide.

Extreme now has an entire line of Powder Coated Cabinetry and Benchtops available in three stock colors (White, Spectrum Gray and Black) and is available in any color under the rainbow for a slight upcharge. Powder coating protects our Industrial MDF products from chips, stains, spills and scratches, provides a durable, seamless finish, as well as being much more moisture resistant than the typical garage cabinet.

One of the biggest breakthroughs for powder in the heat sensitive substrate market is on medium density fiberboard, or MDF, a combination panel bonding
particles of wood with a synthetic resin.

MDF is very suitable for powder coating application because of its low porosity and homogeneous surface. MDF products include garage cabinets, office furniture, kitchen and bath cabinets, doors, store fixtures and displays, barbecue trays and ready-to-assemble furniture for the office and home.
